This is just an average show. The plot is good and the twist at the end is also good, but there are elements in the drama that made me feel like I didn't care what happened. The female lead was not a good fit..she didn't seem to be able to keep up with the rest of the cast in acting and there was very little chemistry between her and Jinyoung. The pacing is also slow at times..I started to skip watch by episode 10 and didn't really miss a lot. This could have been much better with a fewer episodes.
I also think that shows like 'Just between lovers' and 'Healer' handled storylines of dark past and interconnected secrets way better than this show did.
