For people who have read the original story and enjoyed the first adaptation of Hana Kimi (Japanese), then this would be disappointing. They changed some minor character's personalities and traits and added some of there own to add more drama, or so I think. If you were expecting it to be funny like the first Hana Kimi, then you would also be disappointed because this drama lacks that kind of humor. This version also changed minor minor events, that make the main characters seem superficial, like making the main guy, played by Minho, to be a celebrity and making the girl, played by Sullie, have a more fangirl-like reason to dress up as a boy. Without comparing to the original, I thought that the actors and actresses were decent. I really liked who they picked for the girl role and thought she played her part very well. Also the main male role was also very well played. I wouldn't say that the rest of the cast was mediocre, but because they changed some of the personality traits, like the guy who is supposed to play the Korean version of Nakatsu, I got annoyed with them at times. All in all, the show was made into a good drama, but it's not something that I would deem as very great either.
