I'm lazy as hell but here's a quick run down of Park Jinyoung~ :

 

Jinyoung is a homeless boy that sleeps around with usually older and wealthier men, so sugar daddies, and has just dropped out of high school to continue his "iob" since he was failing most of his classes. Most of his friends turn him down now so he lives a lonelier life style but is almost always a happy go-lucky personality since he's trying to find his next man~
