Yeonjun is a university student. He is one of the most awarded students in Seoul. He is studying to be a lawyer; he knows every single law and hasn't forgotten one in his entire life.

You are his tiny problem. You are also a university student, studying medicine. Your paths cross occasionally, and your relationship is hard to describe... enemies? friends? or just acquaintances?
He loves to annoy you with his legal jargon, and you are too stubborn to simply give in, so frequent arguments occur, though they never turn into real fights.

Most of the time, Yeonjun doesn't want to attend classes; since he always attended and received the highest marks, he sees little point in it. The guy often keeps watch in the hallways, overseeing security; no one cared that this was technically a security guard's job.
