I don't know if the manhwa is that bad, but this drama's story was. It was boring and had nothing new to offer. The love story in the first episodes was really promising and cute. The drama in the last episodes was interesting and thrilling. However, the middle part and the very last episodes were disappointing. I really wish that the plot matched the great performances from the actors. So, four out of ten, because from one point on it was pointless to keep watching it, and it left us with an "open" (?) ending.
