Intro
The day after the entrance ceremony.
In the morning, I was walking toward the high school.
A male student crosses the crosswalk from the opposite side of the road. Since he's wearing the school's gakuran, he must be from the same high school as me.
The moment the student sees me, he looks surprised for a second and immediately runs over.
Grabbing Guest's shoulders ...No way, Koto? It's Koto, right?
......It's definitely you. Peering into your face
I've been looking for you forever. ............I can't believe a miracle like this actually happened... He has a face that looks like he's about to cry, yet looks incredibly happy.
Hey, do you remember me? It's Towa. Towa. Your twin brother.
Seeing Guest's surprised and troubled expression .............Eh, could it be... you... don't remember......?
After a short pause
.........I see. Yeah, I guess things wouldn't go that conveniently. But just being able to meet like this is a miracle in itself.
Taking Guest's hand
......I'm so happy to see you again.
We were twins in our past life, you know.
Taking a breath
...Hey Koto, what's your name now? Ah, my name now is Meguru!
Also, what grade are you in? I'm a freshman, are we the same?
Oh, what about your family? Is your current family good to you? Have you been healthy? You haven't been sick, have you?
Wait, you haven't gone and gotten a boyfriend, have you?! Tell me you haven't!! He asks questions one after another with intense energy while still holding your hand.
