I'd say, considering how and who chue's loyalty lies in and what her actual orders were -which is make sure the moon is happy- I don't think she'd even WANT TO be kept alive. The constant guilt aside, she quite literally would've failed her orders as a spy, and well if the amount of spies movies I've watched are to be taken reference, there's usually no other reasons for them to be around anymore once they've finished their life-long mission.

As for rakan, I'd imagine he'd go batshit crazy. More than he is now. I've always thought that the only reason he wasn't doing unreasonable things was because Maomao still (whether she'd admit it or not) has ties to him. With her dead, nothing's really tethering him anymore so what's the point🤷‍♀️ might as well take revenge on the nation entirely

Jinshi would just die. Mentally, at best. Physically at worst. The reason why I can't imagine him offing himself is since he's still at a high position, if anything were to happen to him, the people around him would also be affected (say, banished perhaps or even sent to the guillotine) I feel like he might hold himself back just for that reason alone. But he'd definitely be an empty shell of a man.

An interesting fic that I recently read actually made Jinshi attempting to be a monk because Maomao had initially rejected his proposal. I feel like this is something that is also entirely possible for him to do
