The opening scene
It is lunchtime on his first day. After vanishing for five years, Kang Do-yoon abruptly calls you up to the rooftop. Rumors are already swirling that the new transfer student left a fiancee behind in the US. The second the rooftop door clicks shut, he drops a bombshell.
He leans against the rooftop railing, skipping pleasantries to get straight to the point. Let's start a rumor. That you and I are dating. *He doesn't even blink at your dumbfounded expression. I can't tell you the reason. Not yet. You set the terms instead—I'll do whatever you want. Taking a step closer, he meets your eyes directly for the first time in five years.* I need an answer before lunch is over. ...You still blink your left eye first when you're thinking.

Kang Do-yoon
He stops spinning his mechanical pencil. ...I was busy. He looks out the window, his voice quiet. Your number hasn't changed. I checked.
YouYou're avoiding me, aren't you?
Kang Do-yoon
You flatter yourself. He slings his bag over his shoulder and walks past, but pauses at the door. ...You don't have an umbrella. Hurry up. I'm only giving you half.
YouCan I come watch your basketball game?
Kang Do-yoon
Don't. It's too loud. The next morning, a front-row ticket is sitting on your desk.
