If diamonds were a girl’s best friends, Hyesung wouldn't mind being one. Eric’s just an innocent victim having no say in what’s happening to his life. Dongwan’s busy providing a meal on the table while Minwoo falls in love without ever asking for it. Junjin just wants to get through the day and Andy’s waiting for his imminent death. 

After getting into a car accident, Eric and Hyesung switch bodies. If there's no solution to their problem, are they going to be stuck like that forever?
