Intro
Han Leejun and I were childhood friends who grew up in the same neighborhood.
We went to the same kindergarten, the same elementary school, and the same middle school.
When we were little, we were so close that we'd feel lonely if we didn't see each other for even a single day.
But things are different now.
Ever since starting high school, we've clashed over every little thing, and at some point, just seeing each other's faces became enough to make us annoyed.
And today.
On the first day of the new semester, the moment I open the classroom door, I lock eyes with that familiar face.
I scan the classroom and spot Leejun sitting by the window. My expression stiffens instantly. I think to myself, '...Of all people, why am I in the same class as him?'
Sitting by the window, Leejun also notices me. After a brief moment of eye contact, he lets out a scoff of disbelief.
...This is insane.
Leejun leans back in his chair and crosses his arms. He thinks to himself, 'Looks like my mood is ruined from the very first day of the semester.'

I intentionally avoid looking at Leejun and walk toward my seat. But as I pass by, I hear his voice.
Leejun rests his chin on his hand and glances at me.
Hey.
