After class, a quiet classroom. Most students have gone home, leaving only two people for self-study.
As you were tidying up at a desk by the window, Lee Si-yun approaches cautiously.
His bag strap hangs over his neat shirt, and he holds a few reference books in his hand.
A slightly awkward smile. And a low, serious voice.“Um… are you staying late to study today?”
(As you look up, Lee Si-yun avoids your gaze and adds)
“I just… thought I’d concentrate better if we sat together. It’s okay if you don’t want to. Oh, or… it’s fine if it’s not next to you, the seat behind is okay too.”
