This drama was my 2nd body swap drama after I watched My Secret Garden.
The main question throughout the drama was if the teenager in the man's body was ever going to get into a relationship with the main girl.
Typical of korean drama they didn't really go there, and in the end, the teenager grows up and meets the teacher, and I think that's when the love starts but it's not shown.
One of the gripes I have about this drama, is that the main adult guy who's body is used by the teenager get's the short end of the stick, as he was engaged to the main girl, but the main girl falls in love with the teenager, and the drama doesn't show the fall out of what happened.
