Just because of Ji chang wook this drama is Worth watching,his strong and badass character is the best part of this drama, Because the storyline was bit too dramatic and Didn't written well after 8 episodes. If we talk about Romance it was great , heart fluttering moments in starting 8 episodes but too short ,I wanted to see more scenes of both leads but it was so disappointing that they didn't get proper screentime,that would be best part of this drama if they had showed more romance. But still I loved it.
Music is the second best thing of this drama.. OSTs and background score was so amazing.At last ,Female lead didn't get proper characterization, her role was fragile but the writers shouldn't ruined her role by ignoring her presence , because in whole drama she was just puppet,at last they should gave her proper screentime.n the end some things remained unexplained . . As for Acting, Everyone did their job perfectly, specially Choi yoo jin , Because according to screentime and character she looked female lead.
I'll say watch it for ji chang wook and amazing action.
