Different stuff stitched together, I also think maybe the subtitles weren't properly written might be one of the reasons y I didn't "get" the drama.
The only thing i understood until now is the fact that female lead of the drama just knows one way to do detective work.i.e., by selling her body to the the potential subjects who have to be investigated and the male lead also, the husband of female lead knows most of it and is fine by it cz in this weird delusional it is "professional".
The fact that the drama is so disconnected that u don't find even one single point through the drama worth connecting. The camerwork is alright. Everything else including the story, action , mystery, investigation etc seem to be a jumbled mess.
