Bohm, a young boy with a kind heart, is on a mission to deliver a pair of underpants to his father, Detective Ghim, who has been working non-stop for 10 days. As he walks through the police station, he catches sight of a mysterious girl standing by a vending machine. Bohm finds himself drawn to her and wishes to run into her again. Meanwhile, Mahnsoo, a troubled boy with a cryptic past, is forced to assume a disguise as a girl to become a witness to a high-stakes crime. As he is taken in by Detective Ghim's family as a temporary guardian, he is tasked with keeping up the charade until the case is resolved. Unbeknownst to Mahnsoo, this new arrangement will bring him face-to-face with Bohm once again, and navigating his new brother's icy demeanor proves to be a challenging task.
