Not so good but OK

I started to like drama from episode 4 , before that I keep thinking why Kim soo hyun and Kim ji won accepted these roles. Their love story was boring and untouchable. Kim soo hyun’s acting was good as always I also liked Kwak Dong Yeon. OST was good and the other thing I liked about the drama was the atmosphere of urban life but side characters were not so connected with the storyline. Overall it’s worth watching once but not twice .
