Enter Lee Dohan, who claims to be exactly that. But there’s a catch: every time Dohan tries to harm Yoon Dam, mysterious wounds appear on his own body instead. Intrigued by this bizarre connection, Dohan proposes a deal: “Why not just let me be your tutor?” Bound by strange circumstances and their own hidden agendas, the two set off on a journey neither of them could have imagined...
