Honestly I personally enjoyed this version better than the other versions. Choi Minho was too cute and I thought he looked familiar but I totally didn't realize he was from the group Shinee which I like a lot. I thought there were a lot of really cute/sweet scenes and the attraction between the two/three leads was very evident. Kang Tae Joon (Choi Minho) was so cute when he got flustered and was, I thought, a surprisingly good actor. The other boy lead Cha Eun Gyeo was way cute too and I also enjoyed his role. Though there were parts that did fall a little flat and areas where I thought more detail should have been added, over all I enjoyed all of it and I wasn't ever really bored with it at all. I thought it was a bit more serious then the Japanese or Taiwanese versions with not quite as much silliness though it still had its share. Also, it was harder to tell some of the other side characters apart in the Kversion where in the other versions especially the Japanese version the side characters were much more distinctive in their character and appearance, they just kind of got lost in this one. Also, it does tend to stay focused for the most part on the three main characters where the other versions encompassed the side characters more but that is probably what kept me interested as I don't always like to run off on a tangent with side characters to often.
