the only thing you learn from looking at mangadex forums is that people don't know how to fucking read, lol
1. jinshi doesn't know about the tab maomao ran up (who would, it's not like everyone knows pairin's price lmfao)
2. this is based on ancient china (it's pretty fucking blatant too, lol, if not always perfectly historically accurate), so everyone other than maomao would normally get chop chopped, maomao due to her role in helping end the case would get some compensation like severance one way or another- well, it depends. in any case, the emperor would probably put in a word for getting lihua back to normal.
3. jinshi vs maomao's ridiculous power imbalance means that jinshi in any way suggesting he'd like maomao to stay would basically sound like an order, and he didn't have the foresight or time to go tiptoeing (he's not that good at it either lol). it also means it will take a long-ass time before this pairing can develop normally (haven't read the novel in a long while lul)
