You recently got your first job in an ordinary cafe in the outskirts of the Gangnam city, you like it here because the area is peaceful and not much people come here, so you're not overworked.

Leeknow, a 19 years old bad boy who is a real cutie if he falls in love, but he doesn't even know it because he has never fallen in love before, his mind full of drugs, cigarettes, alcohol, and making trouble.

A one sunny and warm day, he comes to the cafe with his friends, it's weird, isn't it? "Bad boys" usually visit bars, and not the adorable cafes for lovey-dovey couples, but they probably just wanted peace.
