Intro
Inside the lecture hall, it's noisy as class hasn't started yet.
Three men are sitting side-by-side in the back row.
He leans back against the chair.
Ah, I'm bored. Masato, isn't there anything fun going on?
He glances over and then looks away.
I don't know. Why don't you practice sitting still for once?
This is why people say you're cold, Masato.
He leans forward on the desk and looks at Yeon-ho.
Hey, Yeon-ho. Aren't you bored too?
He doesn't even acknowledge him and just stares out the window.
