On the June 28th episode of KBS 2TV's 'Win Win', singer�Kim Bum Soo shared details from his rebellious adolescence. The singer compared his past to his current state, having recently risen to a new level of popularity after taking part in MBC's 'I Am A Singer'. One of the discussion topics on the show concerned rumors that Kim Bum Soo was a notorious fighter when he was in school. Kim responded to this rumor, "That's a little misleading. It's true that I fought often, but that doesn't mean I won them all," and jokingly added that in reality he was a cheap fighter. Delving into his rough past, the singer explained that after his father's business failed, his entire family moved into a small basement room. Kim Bum Soo said, "I just went around getting into fights all the time." He added jokingly, "I think my extreme cheekbones and pointy eyes formed as a result of my rebellion." He continued, "I'm not the type to pick a fight if I'm left alone. It was only when someone would look at me the wrong way or touch me that I would get angry. I think I used fights as a defense mechanism because I had so many insecurities about not being as good as other people." Throughout his troublesome youth, the singer admitted to having frequented police stations. While describing his dramatic about-face in life, Kim Bum Soo revealed, "I quit smoking and drinking and changed my entire life after I contracted pleurisy (an inflammation of the lungs that causes sharp chest pains) my senior year of high school."
