I get where the writers were trying to go with this drama, but I don't think it was executed very well. First, the development of the story and the characters was too slow. I take points off because they had to "narrate" at the end to explain the point of the drama when they could have used more plot and character development to explain. When a writer has to do that, then I feel the story wasn't developed well. As for the acting, I think all of the actors did a great job with their characters. None of them really looked like high school students, but it didn't matter. It was pretty much an all star cast. Too bad the veteran actresses stole the show. Kim Ki Kyung as Eun Sang's mom and Kim Sung Ryung as Kim Tan's mom were just too funny and their relationship was fully developed and fun to watch. I enjoyed their part in the drama the most. The music for the most part was just horrible. I won't rewatch this. If you are looking for something that doesn't make you think and you want to see hot guys...Lee Min Ho, Kim Woo Bin, Choi Jin Hyuk, Kang Ha Neul, etc...then this is the drama to watch.
