Singer Sung Si Kyung featured as a surprise guest on the November 15th episode of KBS 2TV 'Win Win' alongside female singer Park Jung Hyun. When the MCs asked him if there are any that approach Park Jung Hyun, Sung Si Kyung replied, "I didn't actually tell her, but... I did receive one phone call. He's a celebrity too." Sung Si Kyung dropped a few hints as to who the mystery man could be, revealing that like Park Jung Hyun, he was also in his thirties and was also a musician.�The MCs further probed him to at least drop his last name, but Sung Si Kyung revealed too much by responding, "If I tell you his last name, it's over." The guests and the MCs brainstormed and decided it could possibly be Leessang's Gil, but the singer quickly changed the subject, causing the set to explode in laughter.
