I really liked this drama. One reason is because I've been searching for exactly this story - reverse roles of the usual drama where the girl is the innocent, sweet person and the guy is the cold, self-centered one. I also liked it because none of the characters were morons or annoying IMO.
Also, it had kissing. I haven't really seen Japanese dramas having skin contact much, and that kinda annoys me. This drama didn't have that anime feel to it either, which I like sometimes, but I know alot of people who don't like Jdramas because of that comical way they talk and stuff. Oh yea, I liked the ending ;D
Overall, I would recommend this drama to all. It was nice to watch. Blah... now I want to find a similar drama!
