I watched this and I must admit I found it surprisingly good ! I wasn't expecting much but the fact that it is a much "adult" movie made me want to watch it to see how korean portray this kind of movie. And well, they did it good, the sex scenes are just in the beginning and it's not all about sex, there's a real story that goes on. The chemistry between the two main characters is what made me melt, especially Ji Sung's expressions when playing his character. The music is also awesome, especially the end song , I was once again suprised in the best way ever. As an overall, you can expect the outcome of the movie but not really the way it ends (if it makes sense, watch it and you'll know what I mean). I would definitely rewatch this movie as it was refreshing, funny,and realistic.
