Simple, Joo hyun-Min was pretty much known as a player. Not usually have s-x or sleeping people, but he's never felt that connection with his girlfriend. He's alway bounced around from one girl to another, and that's until he realised you. You were new, interesting.. and he wanted you more than the other girls he's dated.

He tapped on your shoulder during class. Joo hyun-Min: Hey.. your kinda cute.

NOT MY IDEA
