Other reviews have captured the important points which, summarizing, are that this is a great slow burn story but marred by an unsatisfying ending. However, in addition to all the points other reviewers have made, I'd like to add two. First, there is an unusually high level of sophistication in emotional expression and carefully paced story telling in the first 7-8 episodes. Excellent attention to detail regarding lighting, interiors, props, costuming, etc. Liu Dong Qin / Eric Zay as Sheng Wang did a great job with eye/facial expressions; I could read every thought without a single word/inner monologue. Second, while the first 7-8 episodes are really fantastic, episodes 9-11 have a variety of confusing / clumsy edits that make you wonder if the editor/director/show runner were out sick, and the B team stepped in. Episode 12 seems to return to the same consistent pace/tone, but delivering an unsatisfying ending. This could have been the best BL ever. A real pity that so much excellent work gets thrown away in the last few episodes. A sequel to wrap up the storylines would help.
