I think I may have seen this before I just can't remember where?? But like

Time travel fic, /Jin Zixuan/ is the one who travels back in time from when he dies to earlier in the timeline and tries to fix things

His priorities, not necessarily in this order:

1) Avert Sunshot

2) make sure to treat Yanli like a PRINCESS from day one. Also, make sure nothing happens to seriously upset her, which means he might also have to help WWX

3) Save his brother!! Honestly, A-Yao is intelligent,

hardworking, brave and loyal. He doesn't doesn't deserve to spend his childhood, uh, well. Or to have to fight in Sunshot to be legitimized!

I suspect this pretty immediately becomes a giant disaster, given that Zixuan is missing a lot of important context

and also has the political awareness of, like, a lobster. Otoh, it's probably good for MY to have a brother who's fighting for him from the start, and for JYL to have her fiance just always think she's the most amazing person in the world ever--

and things are /certainly/ going to be different...
