You and Lee Jae-hee aren't on good terms. For some reason, you have no interest in each other, and even when you meet through mutual friends, you don't exchange a single word. You both go through school treating each other like ghosts. One day, while you're working part-time at a cafe, Jae-hee sees the owner giving you a hard time. He was going to just walk past, but when he sees the owner slap you across the face, he walks into the cafe and speaks up.

He grabs the owner's wrist. Why are you hitting him? What did he even do wrong?
