It's a Chastity-Reversed World, But It's Different From What I Imagined? - 12

Chapter 12: Childhood Friend’s POV: 1

ーーーーーーーーーーーーーーーーーーーー

【Yuuna Aoyanagi】

I had someone I promised to marry since I was little. It wasn’t an engagement decided by our parents though. It was a promise I made in my own heart.

That was when I was two years old. It was when I met a boy that I became aware of this world. His name was Yoru Kurose-kun. My most beloved.

We met because our mothers were friends, and they wanted us to become friends as children. In this world, boys were rare, and as a little child, I didn’t even understand the difference between sexes. But on the very day I became aware of things, I felt it.

“Let’s always be together.”

I wasn’t able to say it that clearly, of course. But when my little self said that, Yoru-kun nodded. You could say that was a vow we made for the future.

My world existed with Yoru.

Kindergarten, elementary school, middle school—we went to the same schools all the way. Every day, I went to pick him up so we could go to school together. Since he had a younger sister, Tsuki-chan, it wasn’t just the two of us. It was always the three of us, together. But by the time I entered middle school, I started to feel the embarrassment of adolescence.

“Hey, hey, Aoyanagi-san. You’re childhood friends with Kurose-kun, right? Are you two dating?”

As puberty set in, classmates started asking things like that to tease me. I got embarrassed and blurted out:

“N-no way, he’s not my boyfriend! Besides, boys are gross.”

Even though my heart felt the opposite, I denied it. It wasn’t like Yoru heard me say it, so I thought it was fine. But I hated being teased by my friends, so I started to keep some distance from him at school.

I began entering swimming competitions, something I had practiced since childhood, and I was able to win. But from middle school on, Yoru started acting strangely. He was never good at talking with people in the first place. Apparently, he messed up during self-introductions, and ended up isolated in class.

Since we weren’t in the same class, and I was keeping my distance at school, plus with morning swim practice, I couldn’t walk to school with him anymore. Little by little, I had less time to see Yoru. Even so, almost every night we exchanged messages on Main, so we kept in touch.

But still, the distance between me and Yoru kept growing. When I was feeling lonely about that, Tsuki-chan, Yoru’s little sister, came up with a plan to protect Yoru from other girls. Sometimes Tsuki-chan stayed over at my house, and we talked about Yoru.

“Yuu-nee, you don’t understand just how endlessly cool Onii is!”

Tsuki-chan was someone with a severe brocon. I understood her.

“I know! I know, Tsuki-chan. Yoru is insane! You know what’s insane? Having that kind of sex appeal in middle school! A mature face. A body trained since elementary school and because he’s bad at talking, he gives off this taciturn and cool vibe. Everything about him is downright erotic!”

Things I was too embarrassed to say in front of other kids, I could say freely in front of Tsuki-chan. I didn’t mind sharing Yoru with Tsuki-chan.

“Now that he’s in middle school, he looks even more mature, doesn’t he? Since I’m his childhood friend, the kids around me keep telling me to introduce them to him every single day.”

Ever since I said he wasn’t my boyfriend, lots of girls had asked me to introduce them to him. Every time, I politely refused while secretly feeling irritated.

“The girls in his class still haven’t spoken to Onii yet, right?”

“Ah—that. That’s because during Yoru’s self-introduction, he was too embarrassed to say anything. He just mumbled his name and sat down. Because of that, the girls in his class now treat him like some untouchable, sacred being, due to his looks and his quiet demeanor.”

When I told her about his failed self-introduction, Tsuki-chan grinned creepily. She always got a little weird when it came to Yoru. But I heard that a lot of girls with brothers tended to develop brocon tendencies, so I figured it was normal.

“I knew it. When I infiltrated, I saw a few girls looking shyly at Onii. So that means…”

Shyly? What? Other girls were looking at Yoru? Someone might take him away? When I heard Tsuki-chan’s words, my chest tightened with a painful feeling. It was a pain I had never felt before. Since childhood, Yoru had only ever had me. Even with Tsuki-chan, the closest girl to Yoru was me alone.

“You’re going to tell Yoru that he’s gross?”

Tsuki-chan’s plan was to mentally isolate Yoru.

“Yes. Since Onii isn’t good at talking, he doesn’t really get information from others, right?

So if we tell him, ‘You’re gross, that’s why the girls avoid you, so you shouldn’t talk to them,’ then it’ll work.”

If it was just Tsuki-chan saying “gross,” then I wouldn’t be hated. Inside, I smirked. I didn’t want to hand Yoru over to other girls. Not even to Tsuki-chan. She asked me to create a secret ‘Don’t Talk to My Brother Agreement’ among the girls. That was easy. After all, Yoru never spoke to girls on his own. The only girl he could talk to was me.

“I see… Tsuki-chan, you’re a genius! If we do that, it means only you and I get to have Yoru all to ourselves!”

I got the girls from the sports clubs to help me keep other girls away from Yoru.
