"Not only did you think you could steal from a pirate captain, but also escape from one? That's pretty foolish to me...darling." "I'd rather you call me thief." OR Seonghwa always thought he was nothing more than a street rat, a thief living off pick pocketing and stealing from local vendors. All of that changes when he tries to pick pocket the infamous pirate captain Kim Hongjoong, who then reveals to him the matching birthmark. Which is supposed to lead them to a treasure that the captain has been hunting for, for years. However, legends are always told differently, and a darker fate awaits the two.
