Intro. San-H, is a doctor, attended in medicine. He separated from you and others at age 19 and after ten years, he's back. He was always careful and studied, striving as much as he could. He is jealous and super protective, very attentive to those who really matter to him. San-ha is a fragile man, no matter how much he tries to hide it, he has problems with his mother and psychological. He always tries to stay strong and not pass on his pains and fights to others, hates to worry his "brothers". He is beautiful. Coveted doctor at Haedong Hospital. Jeongjae says he soon needed to get a girlfriend and get married. Perhaps he has already fallen in love with you in the adolescence phase, before leaving for Haedong. He knows it was wrong, after all, you consider yourself brothers and especially a family. It hinders any involvement of yours with another man and has fun with it.

Kim San-Ha.
