I went into this movie not knowing what to expect. I'm not a big fan of affair movies and as the title tells you.. this is one hell of an affair movie. That aside.. I actually enjoyed it a LOT more than I originally thought I would. Being a big fan of Uhm Jung Hwa AND Lee DongGun, I had to watch it despite the story and low and behold.. I actually enjoyed it. Like any other affair movie, the story has a very dramatic feel to it once you start it but isn't actually super dramatic and .. sad, which was much to my pleasure. The acting was pretty darn fantastic and enjoyable. For those of you who are familiar with Lee DongGun's previous works, such as his dramas and such.. I'd say this is one of his better movies, knowing he's known to be in duds that really aren't worth your time. He really shown in this drama though, his feelings being written all over his face for his leading lady and that really is something to see. Uhm JungHwa always shines in her works so I have nothing more to say about her acting. As for the other two.. well that just leads into the next factor I'd like to address about this movie. In every drama or movie you watch there are usually four main characters in the romance department. Obviously, the same goes for this movie. It's hard to watch a movie like this and not pick favorites. As I saw it, this movie really tried hard to give equal time to each couple and express the attraction between the couples equally but I really felt more involved in JungHwa and DongGun's romance than the other two. Although both couples really felt attracted to each other I have to say these were my favorites and were fun, sad and pretty to watch their love bloom as well as the drawbacks of having an affair. That heartrending decision they both (kinda) had to face. As for the music, most of it was quite lovely and it all, I felt, fit into the scene that was occurring, making it either more dramatic, hyped up, or melancholy. I'd rewatch this movie a year or so after I saw it, if I felt like this type of storyline again. It wasn't super entertaining to the point where I'd call it one of my favorite movies, but it was cute and romantic and I'd recommend it to a friend, rather than re-watch it myself, I think. This movie isn't for everyone, I'd say. Those who don't enjoy affair movies, I'd definitely not recommend it seeing as it's about betrayal to your partner as well as a deep connection with another person you barely know. The movie is also a tad racy and there are some nudity scenes so if you're younger than 15, I don't recommend watching it without your parents permission.
