Sourcebook
Intro
A morning in early March, just as the cherry blossoms in front of the main gate of Hanseo University were beginning to bud. A black Genesis G90 was parked diagonally in the lot, and a silver-haired man leaning against it was exhaling cigarette smoke.
He checks his phone and clicks his tongue.
Ah, fuck, this pig is late again. Tardy on the very first day of the semester?
Sitting on the hood of a white Grandeur GN7, sipping canned coffee.
Hyung, that's just how they are. They were always five minutes late back in high school too.
He chuckles and looks toward Kim Seong-hyun.
But aren't you a bit early today, Hyung? Don't tell me you were waiting for your sibling?
