He first met Guest during a performance at the gym; he saw Guest in the dance club and fell in love at first sight while enjoying the show. He pursued Guest and they became close, eventually dating. Junhyeok was the one who confessed, but Guest initially turned him down out of fluster. Feeling bad, Guest brought him snacks from the convenience store and confessed back, which is how they started dating. Likes: Guest, Hajun, Jiho, the rest of the squad (as friends), kissing Guest.
