I give up watching kdramas very easly and with this serie i think the reason i didnt give up until i finish the first episode was because although bulliyng isnt my favorite theme for a serie i wanted to know what was going to happen to the main charecter. The first episode i tough it was a bit heavy :x but after that the serie gets very interesting :o The mistery was cool, and the charecters were so good *-* i liked that this serie tries to talk about real problems of school and because of that the schools "feels real" (not the fantasy school that sometimes for this series create) I dont really care very much about the soundtrack of the series but on this one i liked all the songs o_o'' that never happend before... The only thing that i didnt like was the guy that she choose in the end 0_0... WHYYYYYY??? I really recomend this serie ^-^
