I rarely write a review, but this time it deserves a review. The acting was soo good, the transition of each story is seamless. I've watched a lot of drama's and the common mistakes of dramas are the execution of the twist. The story is complicated but it was presented in an orderly manner. The pacing is subtle, enough for the audience to build emotions.
The director has a very good cast ensemble, as for the actor who plays "Pharm" your crying skills sold the series.
