The trailer and the synopsis defo do not do this movie justice. Let me say that first. DO NOT count on them for an accurate description. You expect comedy because of JJS, but i should have known because Do Kyung Soo isn't that type of actor(if you've seen other shows hes starred in you'll understand). The movie makes you smile and doesn't waste time on trivial filler bits, even Park Shin Hye i would count as a supporting character rather than a main as it wasn't about her. I don't want to say too much because its one of those movies you have to watch with no expectation so that you can get the full impact of emotions. Music wise, there wasn't much but the closing song was sung by both male leads, which is cute. I would definitely re-watch as it didn't even seem that long. Really enjoyed it **WARNING** Make sure you have tissues handy
