It’s a classic setup gone wrong: the neglected boyfriend, the pining younger student, and a hidden exhibitionist streak. When Jisu decides to punish his boyfriend Hyeon-oh by seducing his student Hyeonjae, he thinks he’s the one in control. He offers up his pierced body as a playground, only for Hyeon-oh to walk in and join the fun. Caught in a web of obsession and sibling rivalry, Jisu realizes that his birthday wish for more love might have just come true in the most deviant way possible. The game is no longer about jealousy, it’s about just how much Jisu can handle.
