This is one of the few reviews I will write but omg everything about this show was so good, the variety of casting with wi ha joon and lee do hyun. The premise is really unique too for the time, he goes back in his 18 year old body and tries to fix the problems in his life basically. The story was well written and I just don't know why this isn't more talked about still. Lee do hyun's acting is never bad and the children were also such a joy to watch. I know the age gap is a little weird but I didn't mind it at all since it was him just in a better body :D. That 's all I will say, I will continue to watch lee do hyun's dramas.
