Summary: To Yishan, Sangshen is everything. So, when the doctor said that the winter weather of LoES would weaken his beloved and make her pregnancy harder than it should be, he packed his bags, left behind his title as Clan Heir, and moved somewhere warmer. It ends up being FFM.
Or: Yishan moves out of his parents' house and gets a job. Sangshen lives and reunites with her long-lost brother. Yue ends up with five parents and one annoying guy who loves her Mama very much.
Some things about this AU:
Just to preface: Yishan has little to no character development. He remains his wife-obsessed asshole self throughout the entire AU. He has no paternal bone in his body and never develops one.
Moving to the exact island where Sangshen's little brother lived was by complete accident. Yishan just wanted to take her there since he heard it was paradise.
The entire reunion was tearjerking. Macaque has a family who never stopped loving him and Sangshen got her brother back.
Wukong and Macaque were there at Yue's birth and were one of the first people to hold her (Yishan wasn't interested.) They adored her immediately and Macaque cried when he's told she was named after him.
Yishan got to have an official wedding with Sangshen and make her his legal wife like he's always wanted. She made a beautiful bride.
As a citizen of FFM and not Clan Heir, Yishan needed to pull his own weight to provide for his family. Thankfully, because he was Clan Heir, he had skills that put him under Liu's command.
Surprisingly enough, Liu manages to get through Yishan's difficult personality and becomes his first and only friend. (No, in-laws and their not-yet-lover/king don't count.) They have this bromance thing going on, though Sangshen still lingers in 90% of Yishan's thoughts. But Liu has the honor of having a consistent 5%.
Yishan eventually chills enough to form healthy(?) relationships outside of his wife. He also provides for his daughter. Just not emotionally, which is fine since Yue is loved enough already by literally everyone else.
Yishan and Beng butt heads a lot. Actually, Yishan gets under almost everyone's skin because his personality is terrible to everyone except Sangshen. FFM eventually just accepts Yishan having a rancid personality. That's Yishan.
To the shock of everyone, Yishan was the one to get Shadowpeach together. And then, everyone ended up not being as surprised when it turned out that his agenda was to have Wukong and Macaque distract each other to cut down on time his wife's attention is away from him. Yishan is well known for getting the impossible done for the sake of his wife's time and love.
Trade agreements, alliances, battles - all end up successful when placed in Yishan's hands as long as it has something to do with his wife. He makes it happen.
Yishan can also be charismatic and friendly to outsiders and/or enemies in order to manipulate them. Does it often while he's on the job. FFM as a whole was thrown in a loop the first time it happened. They were all like: who??? r u????? Where's our rancid wife-obsessed monkey????
Yishan hates Azure. Yishan knows himself. He embraces it. But another person like him? In HIS slice of heaven? Threatening HIS wife’s little brother’s love life? Hahaha, no. Sangshen already planned out the wedding gifts and is making the wedding veil. No way.
Yishan has HUGE beef with Peng, which started after they accused Macaque of begetting a child with Yishan (The Brotherhood hadn’t met Sangshen yet and believes she’s fake lol). How DARE they accuse him of sleeping with anyone other than his wife?!?
Shanzha is still sent over as a bride at some point. Heaven express-shipped Yishan's little sister. She isn't received with suspicion. Instead, it's with pity since they knew how much LoES messed Yishan up by then. Sangshen is happy to see her again. Yishan wants the gift receipt to return her but reconsiders when he realizes that she can be another babysitter (more undisturbed time with wife).
The one and only time Yishan does the impossible for anyone other than his wife is for Liu. He somehow manages to pull RinRin from Diyu by employing the help of the Red-Buttocked Baboon (and the Long-Armed Gibbon is there too). Whoops, accidentally acquired a girlfriend for his sister. Well, at least she's distracted now too. And Yue gets another babysitter.
Honestly, Yishan makes a happy ending happen with his own hands soley so everyone would leave him and his wife alone to spend together. That's it. That's the plot.
Extra Fun Fact: Yishan spends every Spring Season wooing Sangshen as if they were unmated monkeys. Say what you want about him, but this man loves his wife.
