Got so bored halfway through and had to force myself to finish it and only by skipping through more boring parts. They could have made it 10 episodes (1/3) shorter. I did really like the twists and turns with Jung Hyun Soo's story and the actor that played him did an incredible job. Really all the actresses and actors did a great job. They were able to convey so much feeling, gah, I mean Ji Chang Wook and Nam Ji Hyun were the main characters. That is all that need to be said. They were the reason why I came, and the reason why I stayed (and for Hyun Soo. Bad characters are even harder to act out). I particularly loved Na Ji Hae and Eun Bong Hee's relationship/interactions. and Eun Hyuk and Section Chief Bang.
Still, they could have 100% left the drama about their fathers out.
