SG Wannabe's Kim Yong Jun recently confessed a trivial reason as to why he broke up with an ex-girlfriend during his adolescent years. On this week's episode of KBS 2TV's 'Happy Sunday', the female participants of the show were complaining about why guys break up without a word, to which Kim Yong Jun replied, "In high school, when I saw my girlfriend's armpit hair, I broke up with her without saying anything." He continued, "It was spring at the time and I met with my girlfriend, who was wearing spring-wear. She was really pretty with straight, long hair." "She was wearing a short-sleeved T-shirt, and when she lifted her arm to brush her hair over, I happened to see a skunk where her armpit should be. I was so shocked. I couldn't tell her directly, it was that much of a shock for me." Kim Yong Jun ended his comical story with, "So in the end, I didn't pick up any of her phone calls and we broke up without saying anything." Source + Photo: Newsen
