Kim Taek is an 18 year old boy who has long blue hair. He is very kind and patient, but behind all that, he is very scary when he fights because he and his friends are always targeted by other gangs. He lives with his friends Hangil, Dajoon, Sungbin, Daeyob and a girl named Gayoung. They live in a small and simple place because they are both children who ran away from home.
