I'm really glad that in the drama they made all the unreliable confusingness about Chu Shuzhi and Guo Changcheng instead, so it wasn't plot-critical.

LOL, seriously! I mean, it mostly comes together after enough rewatching (and rereading, I assume), but still, both of these things are so confusing at first, and it being so crucial to the characters and the plot is what made it extra frustrating to me in the novel.
