Azare, a queen whose life was threatened by her younger sister, Camellia, who had fallen in love with Azare’s husband, His Majesty Aristoche, thinks “If I could have switched places, I would have done so…” It seems that God heard these sisters’ wishes.

---

“Your Majesty, please be merciful…!!!” I clung to my husband, the King, with all my might.

The King gently placed his hand on both of mine, looked at me beside him, and smiled. But in a split moment, it shifted into an ice-cold expression as he looked down from the elevated platform.

Below was my lovely sister, Camellia, surrounded by soldiers.

His Majesty glanced at my sister, who was often called a fairy, as if she were an insect, and then said a few words. “For the sin of trying to assassinate my queen and your sister, someone who you were supposed to treat as family… You shall be burned at the stake.”

“I, I’m safe and sound— I do not wish for such a grave punishment against my only sister!! Please, I ask for your forgiveness…”

“I don’t need help from the likes of you!!” My sister glared at me, with her eyes burning with hatred.

Eh, wait a minute. Hey, sister, I’m trying to negotiate with my seemingly kind, outwardly perfect, but black-hearted husband here. So read the room and try to cooperate for a bit!!!

“That’s right, Azare…”

“No, uhm, my sister…”

“I’ve always hated you. You always got in my way. Why is it you and not me who is next to His Majesty!? Just because you were born only mere seconds earlier…”

What!? No, no way, you were in love with a man like this!? I should have been giving you a Noshi from then on!

“I couldn’t do anything because my body was too weak, so you were the only one allowed to receive the queen’s education. If only I had been born before you…!!!”

“I would’ve chosen Azare regardless of who was born first.” His Majesty wrapped his arm around my shoulder and kissed me on the forehead.

Stop it. Are you crazy?

Now, even if the sinner [Camellia] was in front of us since it’s time to give out the punishments… Is this just part of some act?

“…Your Majesty…” When I glared at him, His Majesty just laughed and said…

“Well, as Azare said, I should be thankful that my queen was lucky enough not to have suffered even a single scratch. So, let’s just settle with a hanging instead of burning you at the stake.”

Hold on!! I can’t see a single shred of gratitude?!

Sister, did you really… like a man like him…? Ah, then I want to switch places with you. If, if I were you…

---

“…”

Hm? Hmmm?? I wonder — was I just having a long dream? I got out of bed and looked in the mirror.

…Uh?

In front of me was my sister, who was supposed to have already been punished, standing with a dazed look on her face. Even the dumbed-down expression on her face, which was comparable to a fairy’s, did not spoil her appearance.

But she seemed young. Too young.

This must be what she looked like when she was about 10 years old. I turned and looked back at the bed I woke up in.

…Where “I [Azare]” was sleeping on. As I thought, she looked to be 10 years old, the same age as my sister [me]. I never thought the day would come when I would see my own sleeping face.

…That’s not!!

No, no, wait, wait, what’s happening!?

If I’m not mistaken, my sister and I only started sleeping in separate rooms when we were twelve years old.

When His Majesty and I… I was already with His Highness at the time, but anyway, it was after I got engaged to him that we started sleeping in separate rooms. We got married at the age of sixteen. There since have been numerous assassination attempts on my life, and at the age of eighteen, my own sister…

“Uhhh… Nnnn…”

The person in my [Azare] body started stirring awake, making my shoulders jump up. When they finally wake up, they will undoubtedly be as surprised as I am. Or rather, I wonder who’s inside me [Azare’s body]!?

I [Azare’s body] opened my eyes slowly and saw Camellia [me] in front, staring at me [Azare’s body] with a stiff stand and a stern look, making my body harden as well.

“…Eh? …Why, why am I…?”

My [Azare’s body] complexion turned pale and pointed to Camellia [me] with a trembling finger.

…Ahhh, God-sama. Thank you for listening to my wish.

I, Azare, became my sister Camellia. My sister, Camellia, became Azare. Only the inside were changed, and we were able to restart our lives again, beginning at the age of ten years old.

---

“Camellia-sama!! You forgot your hat!!” The maid was in a hurry and chased after me.

I’ve been living as Camellia for three months now. Finally, I’m getting to the point where I can naturally turn around whenever someone calls me “Camellia”. However, sometimes there are still gaps, and turning still takes a beat. “Thank you very much.”

When I received the hat with a smile, the maid asked, “Have you applied sunscreen?”

I put on a smile to cover up my mistake. Camellia was pale and fair-skinned because of her weak constitution, but I didn’t think she had also wanted to wear so much sunscreen. And five times in one day, at that.

So even if I never go out for more than one hour, I still have to apply it five times every day![1]

As someone who didn’t even use a hat, let alone sunscreen, it was torture for me to have to spend so much time on such things. Given that, whenever I saw Azare [my sister] looking at me with a subtle expression, I’d say to Azare [my sister], “I’m not going to use it anymore, so I’ll just give it to my sister.”

It’s more like returning it than giving it up.

Once our lives had been reset at the age of ten, we decided to reconcile. Rather than reconciling, we had no other choice but to get along, at least only on the surface. Be that as it may, the balance was divided soon after.

I’d be happy if my sister could live freely, but I couldn’t fully trust her.

At any given time— It’d be too late if I were to get seriously ill, and my sister felt the same way.[2]

We promised not to interfere with each other. If the situation continues, my sister will be engaged to His Highness Aristoche in two years and married in another four. I would never interfere with them, and if anything, I can also get married at the same time to another member of the opposite sex.

I heard that Camellia didn’t become a queen candidate because of her illness, nor was she able to engage with others of the opposite sex. However, since I came into Camellia’s body, I have noticed that Camellia’s physical condition was different from that of a simple weak constitution.

Over the past three months, I noticed that the palpitations, shortness of breath, body ache, and dullness vary considerably depending on the moon’s phases. The magic that overflows from her was too much for her body to bear. “I wonder if I could find a good book on magic control today~”

I realized it for the first time when I became a Camellia. Camellia has a vast amount of magic. Her body as a vessel couldn’t handle it and is being broken down from the inside.

“Camellia, you had such beauty and incredible magic. As long as I can control it, I’m sure my life will be a rosy one!”

…In our first life, she wasn’t aware of the magic that dwelled in her. She shut herself up in her room, envying me as I was always running around outside, unable to forgive her sister, who became the queen even though I wasn’t as beautiful.

…In our second life, you are neither beautiful nor magical, with only health as your merit, so I definitely want you to accompany His Highness, who you are in love with.

Naturally, without me trying to assassinate her. I’m going to live happily as Camellia. As I was reading a book in the Royal Palace’s Library, the chair in front of me was suddenly pulled out. Unintentionally, I looked up and muttered an “Ugh”.

“Lady Camellia, you seem to be feeling better these days? It’s rumored that the fairy finally flew out of her room and made frequent appearances at the library.”

“…Your Highness, Aristoche.”

In front of me was His Highness, my ex-husband, who became almost ten years younger like us, sitting down.

Eh? Why are you sitting down? I, I’m busy. Do I really have to deal with you?

“…A book about magic control? How rare.”

What’s rare is meeting His Royal Highness, whom I’ve never seen once in the last three months.

…However, I’m fully aware. There is no mere “coincidence” in anything His Highness does.

…I have a bad feeling about his, so I better get out of here.

“I’d hate to disturb Your Highness, so I will…”

“Ah, come to think of it— I bought some cookies from Hartz’ Store. Would you like some, Lady Camellia?”

“…!!”

…Damn it!! Of all places, it just had to be Hartz’ Store!! Cookies—!!

Moreover, the packaging that His Highness granted me a glimpse at was a limited-time-only product.

“…I, I’ll have a little bit then… Thank you, I’ll receive it gladly.”

Thank you very, very much. His Highness was smiling at me with his cheeks resting on both hands.

“…Azare has been strange these days.”

I choked. “Cough!! Cough!! It’s… Strange, what, what do you mean by strange?”

“I thought she always had her eyes on the cookies at Hartz’ store, so I brought some to give to her, but she just said, ‘They’re fattening, but your feelings are enough,’ and never ate some.”

“Is… Is that so…”

Oh, I guess my sister is keen on losing weight. That was so like her; it’s her hobby. I still can’t understand it even now.

I answered with my eyes closed. “…I apologize for that, Your Highness. I recently lent my sister a book, so she may have developed an interest in beauty then.”

“…I see. She’s also started imitating Camellia by applying sunscreen several times daily.”

“…I, I have given her some of my sunscreens. I’m sure my sister just wants to be beautiful for His Highness.” I’m sure that it’s the truth.

It seems that my younger sister [Camellia], who has now obtained a healthy body, has already asked our parents to receive the queen’s education and is working hard every day.

—I, on the other hand, didn’t like that kind of education, so much so that even after we got engaged, I kept running away with any excuses I could come up with. Three months before our marriage, my angry parents resorted to half-confining me to forcefully undergo and take it.

Just being able to be free from suffering that hell for three months already makes becoming Camellia worthwhile.

“…I see. Though that can’t be helped by simply dressing up on the outside.”

“…That, that’s right…”

This is getting dangerous; my facial muscles are…

I wonder if I’m laughing correctly.

Cookies—I’ve eaten most of the cookies, so I should just leave now. A cold sweat ran down my spine as His Highness Aristoche stared at me. “Well then, let’s leave it at that— thank you for the delicious cookies. Please excuse me.” I quickly took and held the book on magic control under my arm. I escaped from the library before His Highness could say anything.

---

“His Highness Aristoche… and my sister…!?”

“Azare-sama?”

“Ah, no, pardon me. Please continue.”

“Yes, then, the role of the princess in this diplomacy…”

Even though I was in the middle of receiving the queen’s education, I almost completely lost my concentration.

It’s not a surprise.

If I looked out the window, it’d be in my sight, even if I didn’t want to, the scene of Camellia [sister] and His Highness Aristoche, who are way too close.

It’s already been half a year since I became Azare, who should have solely received the love and favor of His Highness Aristoche. In another year and a half, I will be officially recognized as the fiancé of His Highness.

However, His Highness Aristoche only frequently came to my room in the first month after I became Azare, but the number of times decreased in the second month and more so in the third… It’s now half a year later, and it’s almost close to impossible for His Highness to come to see me.

Instead, I often see him with my sister [Camellia]. When Camellia, with her beautiful appearance, and His Highness Aristoche, with virtually the same, are side-by-side, they make a picture-perfect scene.

Camellia, who is actually Azare inside, doesn’t care about getting sunburned or gaining weight and is constantly destroying the beauty I have cared for, for so long. And yet, when Camellia laughs, it gives such a strong impression on others, as if a rose had just bloomed in front of them, that everyone can’t help but praise her beauty.

I ran the brush over my notebook as my hand trembled.

It’s alright. I [Camellia] have been excluded from being a queen candidate because my body wasn’t strong enough. It’ll be okay; it’ll be alright.

As my sister in the past, I [Azare] am… The one who deserves to be next to His Highness. Because I know what the future holds, I am doing my best to study to help His Highness as much as possible. I no longer suffer from illnesses that erode my body, and there exists no woman who loves His Highness as much as I do.

He’s kind, fair, and humble… He is the perfect man.

I, even if I have to become someone else [Azare] to do it, I’ll do anything to be with that person.

---

“…It’s nice to see you, Your Highness Aristoche.”

“Hello Camellia, what a coincidence. What are you doing here?”

“Oh, I was feeling a little under the weather, so I took a rest under the shade of this tree. But I’m feeling much better now, so I’ll be taking my leave.” Someone, please do something about His Highness. I remember being followed around a lot when I was Azare, but I had no idea he was also following Camellia around this much. Was he always this free for him to be able to chase behind women all the time?

“I wondered if we could talk a little, without you wearing such an unpleased expression.”

“…By no means, such a thing… I’d be delighted to.”

He made a move first, not giving me the chance to run away. I had no choice but to sit where I already stood.

Earlier, when I was sitting down, I couldn’t notice him approaching. I had just been focused on the procession of the ants for a while now. Ants take good care of their family and friends, and because they have a firm division of roles, so I never get tired of watching them. I remember already being mesmerized by the procession of ants ever since I was three years old. Even though we were twins, my sister didn’t understand me at all.

“The other day, I found a book that Camellia might be interested in, though; it’s in the forbidden library that only the royal family could go in and out of.”

“…What, what do you mean?”

“This. It’s a book called ‘Magic Control in Summoning’.” I, I took my eyes off the procession of ants and looked towards His Highness’ hand.

“…I’m very, I’m very interested. However, I don’t think it’d be a good book for me to read.”

“I thought you’d say that. Hey, Camellia, I’ll issue a permit just for you if you kiss me.” I frowned as hard as I could. Undoubtedly, even if I frown, my appearance must still be beautiful.

“…No, thank you.”

I shot up quickly, patting my skirt as I stood. Oh no, it isn’t like my sister to not even put a handkerchief under her skirt when sitting down. I reflected on this matter as I rushed away from His Highness.

Since becoming Camellia, I felt reassured that I would no longer be tied to Aristoche, but it makes me wonder why I felt so sure?

When I was Azare, around the time when we had just gotten engaged, I was at the hands of Aristoche. Against my will, in Azare’s room. His act of whispering “I love you” while doing such an act was gruesome. I kept protesting by running away from the queen’s education, but I already knew. Since I was deprived of my virginity, I’ll have no other choice but to marry His Highness.

However, behind the scenes, maybe he was also messing with my sister [Camellia]. Why, why had this possibility never occurred to me?

Suppose that my sister [Camellia] was being played around by His Highness Aristoche like he’s doing now; I could then understand why she’d hated me [Azare] so much… No, I would have still preferred it if her anger were directed at His Highness instead, rather than at me, if possible.

However, His Highness Aristoche should still be engaged to Azare.

… It’ll be okay, it’ll be alright.

…Everything will be okay… Right?

—Somehow, I couldn’t sleep that day, feeling a little anxious.

---

“His Highness Aristoche has issued a permit, and I’m here to pass it onto you.”

“…Thank you.”

The next day, I acquired the forbidden book that His Highness told me about yesterday. With every page I turned, my fingers trembled. As time went on, I succeeded in suppressing the feelings of doing something I shouldn’t and got so absorbed in reading the forbidden book that the entire day went by, and I wasn’t even able to think about nor eat dinner.

In conclusion, it was stated that there has already been an actual case example of getting rid of a weak constitution due to excessive magic by performing some kind of summoning technique toward the full moon when magic fills the being.

In order to summon, it seems that there is a need to know one’s own ability value (the original amount of magic), the amount of magic exhausted when summoning, and the amount of magic consumed when making use of the summoned being. However, there is currently no available device that measures magic amounts.

It seemed that the only way to learn was to put it into practice.

The day when the moon will be full is in three days. I attempted a simple summoning technique in the backyard of the Royal Palace. I was attempting to summon an ordinary flower fairy. As there’s no harm in trying, nor anything monumental to gain. This was because fairies were the simplest, that even beginners could quickly summon them.

However, the results were… “You are the King of the Flower Fairies… Thank you very much for responding to my summons.”

I summoned something unthinkable. There was a big difference between a typical fairy and the fairy king; it’s comparable to being a commoner to being a king. No wonder executing the summoning took a lot of my magic. However, my body felt somewhat renewed, as if it was in good condition altogether, rather than just feeling refreshed. The Fairy King left the gardens in the Royal Palace in full bloom, regardless of the season.

The next day, I was called by His Majesty. Next to him, His Highness Aristoche was also in attendance. I don’t know what it was exactly, but it seems that what I had done was out of the ordinary. I had no choice but to explain my magic and the summoning details. As I explained, an unpleasant feeling started sounding warning bells within me.

“Hmmm. It’s a wonderful thing that you’re able to use summoning magic. Aristoche, from now on, keep an eye on Lady Camellia’s physical condition as she carries out her summons.”

“…Yes, Your Majesty.” His Highness, Aristoche, grinned.

---

—And then, a year and a half later.

An engagement announcement was made that made me and my sister [Azare] pale.

In the past, “We’ve considered Lady Azare the official fiancé of His Highness, Prince Aristoche. She has been recognized for her healthy mind and body, her qualities that everyone loves, and her sociability and knowledge that were recognized throughout the queen’s education. Above all, she is what His Highness hopes for.” That was how it was declared. Sure enough, it should have been.

Despite that, right now…

“We’ve considered Lady Camellia the official fiancé of His Highness, Prince Aristoche. Her magical summoning abilities that reside in her body have proven to be wonderful and will help the country’s prosperity. Her appearance and behavior, which earned her the moniker “fairy,” are sure to attract the people’s hearts, and above all, she is what His Imperial Highness hopes for. “

And…

Yes, it had already been declared.

My sister, [Azare], collapsed on the spot.

…I wanted to pass out too.

Thereafter, even when I asked to decline the engagement because I might not be able to give birth to a healthy child [successor] because of my excessive magic, he simply did not listen, and the engagement was quickly established between the two families.

I ran away from him as much as I could so that I could try and escape from his clutches, at least until we officially got married… Subsequently, I constantly urged and beckoned him to give my sister [Azare] another chance, but His Royal Highness Aristoche was entirely against it.

My sister [Azare] locked herself in her room, and I was forced to undergo the queen’s education again…

Just like that, I became  sixteen years old and, for some reason, I ended up getting married to the same person.

---

“Camellia, you tried to run away from me as much as you could, didn’t you?”

“Aristoche, Your Highness, I… don’t, know, what, you’re… I don’t know what you’re talking about!!!”

“Really… I didn’t think you’d really make me wait until our first night as a married couple. Even though I quickly wanted to let this body know that it’s mine.”

While his fingers played with the lower half of my body, he kept kissing my ear; his every breath and word kept shaking my eardrums.

It seems like His Highness still intends to commit the same sin toward his young fiancé. It was really a good idea that I never let my maid leave my side, that I faked being ill a lot, and that I pretended to be unaware whenever he sets the mood!!

Well, in the end, I still couldn’t escape from His Highness.

“Hey, since when did the two of you switch?”

“…What are you…?”

“My favorite Azare suddenly started flirting with me. How was that possible? At first, I went along with it because I thought she was doing it as a new form of harassment but looking into her eyes; it felt like she was seriously in love with me. Even though she wasn’t good with it, she kept asking me for a kiss. She was obsessed with her skin that she was usually so careless about, and she wouldn’t even look at her favorite cookies she used to love so much.”

“Nnnfuuu… Ohhh…”

“She began to have a high-handed attitude toward her maidservants; she could not keep her feet on the ground. Even though she hated studying, she suddenly became enthusiastic about receiving the queen’s education. The Azare that I should have loved gradually changed to someone I hated.”

Following a naughty sound, he pulled up his hand and licked at his nectar-covered fingers. And then, with his fingers now covered with his saliva, he played with my flower bud.

“Ah… Ahhh… Ohhh!!”

“…Instead, what came into my view was Camellia. She used to confine herself in her room, gradually losing weight while having a pale face, but then she started to go out more frequently. She greeted people regardless of their status, and although she wanted to leave, she stayed for the cookies I gave her. She started sitting in the garden without a care in the world…”

He stretched out the grain of my flesh between his thumb and index finger. I couldn’t tell whether it was painful or not, I couldn’t tell as I was already on the brink.

“Hyaaah…!!”

“…Hey, did you know? My beloved Azare has a certain habit. She has a habit of closing her eyes when she lies or deceives anyone. And whenever she sits in the garden, she always looks for ants.”

He released the grip on his fingers, and this time, he stroked gently as if it were the prize for being a good girl.

“Above all things, I wouldn’t say that I was perfect. I can’t say that at all… I’ve once heard Azare telling a maid in the past that she didn’t want to get involved because my true nature was a sadistic, black-hearted schemer; after all, my personality doesn’t let me do favors for people that say things they don’t mean.”

“Aris, to, che, Your Highness…”

My thickly flowing nectar soaked the sheets. My thighs, accordingly, had a streak of dripping fluid that felt terrifying permanent, as if it would never be removed.

“…It’s amusing. How only the insides had changed.”

“Hyaaah, uhhh, Nnnaaah… Ohhh!!”

“I don’t care what you look like… I love you.” He whispered breathily, his love for me. When I felt His Highness’ presence leave my side, a warm thing started gliding along the slit of my crotch.

“Hyaaah, Your Highness, that’s dirty…”

“… It’s delicious. Give me more to drink.”

Schluck, schlock, he was intentionally making the sound echo loudly. After, he started sucking on my crutch wildly.

The fingers on his right hand explored the insides of my vagina while his left hand played with my place. I did my best to hold my voice in by covering my mouth with trembling hands, unable to release the heat that kept building up.

“…Here, on this spot. Does it feel good?” I felt my inner walls swell as he persistently stroked and pushed at places that sent unbearable pleasure up my spine.

“Naaa! Ah! Ahhh… Ohhh!!” Sweat rushed down as I felt my thighs tense up, my toes curling in tune with the convulsions passing through my body…

“Ahhh… Ohhh!!”

“Camellia, you did well.” As his bare skin pressed against mine in a tight embrace, a hot, full-bodied cock pressed against my vagina, causing my whole body to shake.

And then…

“Wait, ahhh, ohhh…!! Nnghaaa…!!”

—In one go, he thrusts himself deep inside me.

Before I even had the chance to protest about how much it hurt, he had already repeatedly pushed it in and out, in and out, over and over again.

“…Ca, Camellia… Hey, it’s okay… You’ll get used to having me inside you, so just relax…” His Highness’s unusually rugged voice only worked to increase my sensitivity, bringing in more sensations, surpassing the pain. Perhaps he had noticed my state. His Highness released himself from our embrace and instead grabbed at my waist.

Ahhh, this isn’t good.

Whenever His Highness grabbed my waist, it indicated the beginning of a long, tiring night.

He would continuously make me moan and cry out for him to violate me. He would then persistently penetrate and invade my innermost parts until I whine and writhe, hoping he would do more. And finally, he’d stop holding back and would incessantly rock his hips against me in a drill-like fashion.

By then, I would no longer have control over myself. I’d already be reduced to a mere woman who just wants His Highness’s cock. It was in His Highness’ nature to be satisfied only by making me want and beg him more.

From there on, I would only fall in deeper…

---

In the end, my sister [Azare] did not aim for my life but had suffered from mental illness and is currently receiving medical treatment in the countryside.

When I think about it now, the reason why my sister and I switched bodies and returned to the past was probably due to my sister unknowingly using her magic. At the time, I certainly did want to switch places with my sister, too.

But the result was, in a sense, nothing, as everything had remained the same. I did receive the beauty and magic of my sister, but… I wasn’t referring to that kind of thing…

In the sense that my yandere husband still followed me all my life…

Nothing, nothing had changed.

Sequel

[1] OGAzare thought OGCamellia had to put on sunscreen. OGAzare now realizes OGCamellia wanted to keep her skin that way, so for OG Azare to pull off being in OGCamellia’s body, she still has to do the deed reluctantly but would eventually, quickly, quit, haha.)

[2] That OGAzare might pull an OGCamellia and try to assassinate her, something along those lines
