Lee Dong-gun portrays title character Young-bin, a handsome but obnoxious young man who begins the film by breaking off a relationship in a most impolite way: after waiting in a parked car so Young-bin won't get a ticket, the girlfriend reads him the riot act upon his return, prompting Young-bin to slip into the driver's seat, break up with her, and speed off, leaving his new ex-girlfriend stranded in the parking lot. From the get-go, Young-bin is not exactly a class act.
