What does it take for a guy to get laid, you ask? Well, a hell of a lot of tries is the answer. Lee Si-hyeon is a 21-year-old virgin who has been in the bottom rungs when it comes to getting laid—and it’s not the kind of bottom he aspires to be. After four failed attempts at having sex, Si-hyeon’s fifth attempt is finally successful. Kind of. He wakes up in bed with his former-childhood-best-friend, present-arch-nemesis, Han Baek-kyung. Baek-kyung may not have been the top of Si-hyeon’s list of eligible boys, but he could be the top Si-hyeon needs to undo the curse on his sex life.
