Prologue

“Onii-chan, go out with me!”

“Eh… Haa? Wh… why?”

My own sister, who I can’t say I’m particularly close to or anything, confessed to me out of the blue…

Perhaps it has something to do with global warming, or it is from an old novel that described cherry blossoms in full bloom in Tokyo during the entrance ceremony.

Well, the season of blossoming changes from place to place, so that description is not wrong.

My parents say that in the old days, the flowers used to be in full bloom for the entrance ceremony around here in the suburbs of Tokyo, but for the past few years, the cherry blossoms around here are usually only blooming around the graduation ceremony.

Tomorrow is the entrance ceremony of the high school I’m going to enter. The cherry blossoms in the neighborhood had already fallen and green leaves were starting to grow.

In the evening, in my room on the second floor of my house, I had finished preparing for the entrance ceremony so I was lying on my bed, taking a break and reading my favorite book.

My daily life, which had been uneventful except for the fact that it was the eve of the entrance ceremony, was turned into an extraordinary day by my sister who suddenly entered with a knock on the door, and as a result, my high school life changed completely after this.

“I have a sister my own age, but we’re not twins.”

My sister was going to enroll with me in the high school I had chosen simply because it was close to home.

Kindergarten, elementary school, middle school, my sister and I were always in the same school.

Because we were the same age, people kept saying, “Twins? But you don’t look alike.” To which I had to say, “We’re not twins, I’m the older sibling, so it’s natural for us not to look alike.” So we’re used to such an exchange at every entrance ceremony and class change already.

Just as I was relieved to hear that my sister, who is much smarter than I am, had been accepted to a top school, I thought that my high school was finally going to be different. But to deny my happiness my sister suddenly said to me…

“Ah, Onii-chan, I also prefer to be closer to home, so I’ll go to the same high school as you.” in a very lighthearted manner.

Thus we ended up entering the same high school again for the same reason, and I was slightly fed up with annoyance once again…

Let me lightly introduce myself, I’m Yuu Hasemi, and my sister’s name is Shiori.

Except for the fact that my parents both work and are quite busy and are not home much, we are a pretty normal, average family.

I have heard that my sister is quite smart and is one of the best in the country… Unlike my sister, my self-assessment is that I am mediocre in both grades and appearance. I haven’t found any particular merit or hidden talent so far.

Of course, I’ve never suddenly become popular like the protagonist of a novel, and have never had a confession of love, which makes me always ask myself, “What’s so good about a confession?” The only thing that I can think of is that I got some Valentine’s Day chocolates in kindergarten! How’s that? Good enough, right??

Well… but my sister confessed to me then it stays that way my whole life!

I mean… My very first confession in my life was from my sister…

####

“Uh—, April Fool’s Day was last week, this must be a joke, right?”

“J-joke… I’m not joking! I’ve liked you for a long time Onii-chan… so… go out with me!”

“Going out with someone doesn’t mean shopping. It means love, you know?”

“Of course, I know!”

My sister who was in front of me comes even closer, looking up at me and raising her voice.

Close, she’s too close, but smells good.

“Uhhhh—, why? I mean, we’re siblings, and for siblings to date is…”

“I know that, but, but, but, mouuuuuuuuuuuuuu.”

Tears well up in her eyes as she stared at me with a bright red face.

All I know is that those tears were real…

“Wait, okay, wait a minute, don’t cry. I know you’re serious.”

“Then you’ll go out with me!”

“Why me? You’re already so popular, and I’m your own brother…”

Unlike me, my sister seems to be very popular…

She has long, back-length black hair and large but slightly slanted eyes.(E/N: H**l yeah, long hair)

Her small, thin body is not outstanding, but together with her childlike face, she will be irresistible, especially to those with a very particular taste.

And that’s not enough, she’s bright, she has a lot of friends, so much so that I can’t even compare to mine…!

“Onii-chan, there is no reason to fall in love… love is not something you do, it’s something you just feel.”

“No, even if you say something cool like you heard somewhere…”

“So go out with me!”

“So what? Don’t you see, it is weird for siblings to date?”

“Really? It’s pretty common in recent novels, and in Onii-chan’s manga, they don’t just hook up, they do something more…”

Blushing even more red, my sister said so…

“Wait, my manga you say… what in the world were you reading!?”

Grabbing my sister’s shoulders, I raised my voice.

“Why not? I know everything under the mattress of the bed.”

My sister, didn’t not mind that close look and answered without hesitation, no, that’s not the point!

“Don’t say that!!! That’s a made-up story, it’s not real! Also, give up looking for things under my bed, and don’t enter the room without permission, and don’t search!”

“Ehh—, but on the internet, I saw some people dating as siblings.”

“I don’t know where to start with this, okay, don’t say any more…”

My head was starting to hurt, but I managed to answer, putting my fingers to my temples.

“Will you go out with me then?”

My sister stares at me with serious eyes, her eyes full of tears.

I don’t dislike her, I think she’s rather pretty, but that’s just as a sister.

But I’ve never seen my sister with such a pitiful expression on her face before…

And for the first time in my life, I can’t even imagine how to say no without hurting her…

“Gimme some time to think.”

I chose an answer like a lousy novel protagonist.

I don’t know what to do… for now I need to change my p*rn stash…
