The series sticks faithfully to the novel (which you can find translated at Rebel Scans, though the English is pretty mangled), which is good and bad. Good in that if you love BL stories with tons of plot twists with everyone acting stupid in order to achieve maximum hurt/comfort, then you'll love the series. Bad in that so frequently characters make absolutely no sense as they talk themselves into the next Dramatic Fight.

If the plot makes your eyes occasionally roll so hard they hear the clang in the next valley, watch it for the acting. The two leads are terrific. All the more amazing since apparently this is their first such role. But they are excellent al the way through. Lan Wang Ji is a dancer in real life, and it shows in all his movements, especially in his fight scenes.

The climax is one of the most lugubrious I've ever seen, as everyone stands around for extremely long teary speeches, with occasional sudden stabs so they can bleed, then yet more talking. But the story was not written for plot, it was written for BL, and in that it served its purpose very well.
