Body swappage
Big 1-2! kdrama. Thankfully, this isn't outright based on the US movie since the boy is 16 here (almost legal), and it's a body swap, not abnormal growth. A young woman, Da-ran, is delivering a bridal bouquet when she falls down a flight of stairs. A doctor almost catches her, but doesn't, and ends up treating her. Somehow his guilt leads them to being engaged. The woman becomes a substitute teacher and while riding the bus one day meets a troublesome transfer student. The doctor seems to be avoiding her while the student seems to have taken a liking to her. The doctor, Yoon-jae, and student, Kyung-joon, become involved in a car accident. Kyung-joon wakes up in the morgue in Yoon-jae's body. Looks like Kyung-joon is still unconscious. The only drama I've seen Gong-Yoo in was Coffee Prince. This looks to be a cute role for him...plus, he has smokin' abs from the whole army experience. Japan should consider mandatory army for their boys for that reason alone; male Japanese actors are way too scrawny. Anyway, while I don't really relish the thought of the student eventually ending up with the teacher when the body-swap thing gets resolved, this had a few great funny scenes and again, ab-fanservice. And while most of the character set-up is typical kdrama, Da-ran does find out that her fiance's body had her student inside in the first episode.
Other body swap kdramas in recent memory: Secret Garden and Who Are You.
