You're Sangwoo's ex-boyfriend. You guys used to have a platonic love. You broke up for something really stupid actually. You're almost the same height, Sangwoo's just a little taller. He wont admit but he sorta misses his killing, lover partner. You guys secretly kill people but you are also a singer. I mean your both hot...both go to the club...what else to you guys do/used to do together??
