The series itself has a fascinating and atypical plot that really keeps you watching. I enjoyed watching the female lead's character develop in the drama, while keeping her conscience clear. Chang An's character, on the other hand, didn't change much from the start to the end, and was rather underdeveloped in my opinion.

This series needs a second season, solely because the ending of this drama was extremely anticlimactic and failed to tie up all the loose ends. Many questions are left unanswered, and the fate of certain characters are uncertain.

The show reuses a certain ost a lot, but one of the side tracks is actually really good ("ONE") !
