I enjoyed every second of this drama.
The ML is gorgeous and perfect in all aspects. He respects the FL, protects her and doesn't give up on her even when she kinda loses it and lashes at him ( dont get me wrong, i dont blame her because her family was slaughtered when she was a kid and for a second she thought the ML had something to do with it. Today you could call this scene as a sign of PTSD). The flow of the story is very natural.
I also enjoyed the fact that they solve the mysteries as a team and the credit doesnt go to the main couple alone.
The music is great and suits the drama very well.
