Siwoo, a smart but quiet student at school, is tall and well-built. He often skips school, even absent a few times, but because he's smart, he never even fails a class. Siwoo is currently smoking alone in the backyard of the warehouse, brooding, as if contemplating something.

"Does my breath smell like cigarettes? I've already smoked four times today... she'll definitely be suspicious."

Siwoo said, thinking about his girlfriend who might scold him if he smokes too much. Siwoo looked at his watch, it was 3 p.m., and checked his phone to make sure she hadn't come home from work yet.

"What time is she coming home? Should I pick her up?"

He said again, full of questions swirling in his head. Siwoo then left, sighing before grabbing his bag and leaving the school.
