"This makes it the 562nd time I’ve killed this bastard." Centuries ago, a monster by the name of Shinyoung cursed Dongyi with immortality. For years, he’s done nothing but wait for the perfect chance to get revenge, but killing an immortal is nearly impossible. Trapped in a twisted, endless cycle, he’s long since given up and settled into a strange form of cohabitation with his greatest enemy. But one day, when Shinyoung pushes him too far, Dongyi actually manages to kill him. Shinyoung, who always comes back laughing, doesn’t return this time. An uneasy feeling creeps in, and Dongyi sets out to find him, only to discover that Shinyoung, for some reason, has lost all memories of him. "If you forget about me… then what happens to my revenge?!"

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.
