I put off this movie till now because I was turned off by its title. It didn't sound impressive at all. Once I decided to give it a chance, I was very well entertained. I really like the premise of the movie. Movies or dramas that go back and forth in time all have a similar concept. I rather enjoyed the way it was shown. The two main characters- the younger and older versions were both wonderful. This movie very accurately depicted the feelings and innocence when it comes to first love. The best part about it was its realistic ending. Had it ended in any other way, it would been another one of those cheesy chick flicks where every thing is a fairy tale. It's nice to see a movie which is both heartwarming and realistic. It's hard to find movies like these. It was really well shot and the cinematography was done well. I also loved the cast of the movie. Han Ga In was awesome and looked very pretty. Her character wasn't perfect but I found myself smiling at her behavior and occasional antics. I have seen Uhm Tae Woong in a couple of movies before and he was okay in those. It was hard to believe how old Lee Je Hoon really is. He was perfect as the 18-year-old in love. I would suggest this movie to those who like realistic endings. I myself enjoyed this movie very much and would not hesitate in watching it again (maybe).
