If i have to describe this drama in one simple sentence, then it would be- Drop Everything And Go Watch This Drama Right Now!!

Story:
The story was the strongest point of this drama. It was REALLY a well written and executed drama. One needs to watch it till the end to get every facts correct. Also you should pay attention to every little detail of the drama to be up to date with the story. I loved the suspense, the thrill, the romance- damn it was just sooo great! The romantic angle of the story didn't seem to forced and jelled well with the story. Unlike many so-called suspense drama where the romance takes a front seat and thrill takes a back seat- this drama is a perfect example of how it should be made. It was great!

Acting:
This was my first Wallace Huo drama and I am well prepared to stalk him for next few months. His expressions, awkwardness, dilemma, confusion, love, hate- everything was on point. He portrayed a complex character of Bo Jin Yan with such ease that you would trust in every word he speaks, it was as if he was living this character. I am a fan for life now. Ma Sandra was also great as Jian Yao. I think she did great with emotional scenes. Her presence in Jin Yan's life seemed so effortless that you start shipping them instantly. Also I loved her character, it was good to see a smart and sensible women in dramaland after a long time. That said Fu Zhi Yu was my favorite character. I loved his chemistry with Jin yan. They were friendship goals seriously. He was like a substitute wife/mother for Jin Yan and it was ADORABLE to watch them together. All the other actors were great too. Not even a single actor seemed miscast or did bad at his role. I did wish Wang Kai's character could have been more than it was, but nevertheless all was well.

Music:
Apart from the ending theme which was absolutely great, this drama had an excellent choice of background music. It has such a Gothic feeling to it and helped the audience to build up the suspense.  

Re-watch value:
I hardly re-watch any suspense drama 'cos I already know the ending but I would love to watch the romance scenes from this one. It was so cute and awkward that  you would fell in love with them immediately.

Overall:
Go watch it today. Or NOW! I swear you won't regret it.
