Choi Minki (Ren)

Ren is anti-social and cold, he's never once showed emotion in any shape or form and has never once asked anyone for help. He is cruel and deadly serious, almost like he's dead on the inside. But is that all there is to Ren? Or is there something beneath his empty shell?

Kwak Aaron 

Aron is Baekho's best friend, a pretty average guy whose sole purpose in life is to move out of his step-parents house and live somewhere far away, and perhaps catch the eye of JR as he goes. He's shy and smart, not anything like the 'bad boy' JR is, but he never dwells on many problems in life.

Age: 19

Kim Jonghyun (JR)

JR doesn't show much emotion and id protective over Ren, together they make a very intimidating pair. JR tends to get into fights a lot with his brother Minhyun.

Kwang Minhyun

Minhyun is one of Baekho's friends. He fights with his brother JR a lot due to having different fathers, he feels resentful towards JR since he was the first born and doesn't think JR should be introduced as his brother. He's a bit of a bully, because his mother favours JR over him and blames him for his father laving her.
