First of all, I really enjoyed this show. Binged it easily. The good thing is that they have well defined characters and the plot is well crafted. Being largely a detective story, crimes have to be solved and that leads to clues to the bigger conspiracy as the show progressed.
If you watch a lot of Chinese dramas you will know that most of them suffers from 2 problems, mid show drag and weird plot twists towards the end just so that they can introduce drama (oh how the OTP will suffer) or fix plot issues. In this case, I'm happy to report that the pacing is fine and the main plot did not take a weird detour so that we arrived at the logical end point in good order.
While the story was good in general, the main plot was telegraphed fairly early on and we are just watching to see how the main characters work it out for themselves.
Another plus for the show is that the OTP and the 2OTP have great chemistry and they are steadfast once they confessed their loves. There are no love triangles or prolonged misunderstandings. What angst there is is light and the characters thought it through or talked it out which is quite refreshing. There was a good amount of skinship and hot kisses which were done well (most of the time). It was also nice that the weight of the plot swung between the love line, light comedy and detective story fairly often and smoothly so that you are not getting bored with either. The only slight negative is the acting of the ML (I believe this is his first lead role) can be a little stiff at times but otherwise he is fine and his interaction with the FL is very good. I would definitely recommend this for a light drama with low angst and some nice romance thrown in. Oh final thought. I can't escape the feeling the mains characters are like the setting of a computer game. You have the charismatic leader, the brawny fighter, the healer and the brainy "wizard" :).
