There is lot to recommend this series - foremost the acting, which is uniformly excellent. I'm not sure I've ever seen couples behave more realistically and without reserve - you really felt like these were people with feelings for each other. The physical affection in this is natural and convincing, with lovers sleeping cuddled up and not wearing enough clothing to survive arctic exposure with a minimum of one meter between them at all times like is typical in BL.

There's clearly a lot of passion that went into this production, from direction, to wardrobe, to all aspects of the production, and it makes a huge difference.

The dialog is better than normal, and most of the characterization is steady and consistent.

There are a few issues, however. This is a classic enemies-to-lovers story, and it's at its best - as usual - in the enemies portion, with an interesting and fairly equal dynamic that's unusual and entertaining, with the enigmatic and non-maliciously manipulative Zherui showing up in bizarre and unexpected ways, and the frustrated and grumpy Zong Yi trying to get rid of him while missing him when he's gone. There is no particular seme-uke dynamic at first, which is refreshing, and when they do fall into those roles it's in an unexpected way.

The secondary couple is more clearly seme-uke, but the uke is not useless and without agency. He's crazy and mercurial, and would benefit from a steady-handed partner, but I liked that he's to be reckoned with, not a helpless damsel.

There are, however, a few issues which prevent this from reachingthe top tier. One is the convoluted plot with many holes in it and contrived relationships and coincidences, greatly exacerbated by numerous very large time jumps which plaster over organic resolution of dramatic tension, i.e. the important things tend to happen off-screen.

There is also a silly cliffhanger at the end of every episode and in the middle of them as well. For example. a character is shot, but it turns out with a rubber bullet as part of a life lesson someone was trying to teach which was totally ridiculous. Someone is stabbed, and in the next scene his friends are standing at a bridge with white flowers. To give to him because it was only a flesh wound (to the intestines) - never mind that white flowers are for the dead, and that was just cheap misdirection for 10 seconds of angst. The cliffhangers required a lot of time to be burned on backtracking to fill us in on what happened, and made it very difficult to follow the series if you watched it weekly - so I would recommend binge-watching. As it was, I usually had to review the previous episode because the beginning of each episode is unconnected to the end of the last.

Finally, the dynamic between the main pair descends into stereotypical BL roles, with the formerly grumpy and irritated Zong Yi transmogrifying into a sweet romantic lead, which is frankly boring and inconsistent with the character as originally drawn. He was bound to soften a bit, but he didn't need to become a different person. Clearly the writer wanted lovey-dovey interaction, but it could have been done with some of the edge left in. Due to what happens along the way, he suffers from a short-term memory problem - for about 5 minutes after a huge time jump, then it more or less goes away and has no further impact on anything.

There is a fake memory loss plot that is resolved so quickly that it's pointless and probably should have been left out. The story arc of the mafia boss was very well-acted, but had so little impact that it essentially wasted time. Too much was attempted for the run-time available, when it would have been better to just cut out elements that weren't necessary to the story.

Would I recommend this series? Definitely. Despite the criticisms above, it has so much going for it that the problems are overbalanced by it's good qualities, not least of which the unbelievable attractiveness of the cast - they are all smokin', and even better are all talented and skilled actors.
