Shen Yuan transmigrates into one of Bingge's wives and after an adjustment period it like, ok this isn't too bad actually.
He's not super thrilled with the new body but it's not that bad really. And as long as he plays it cool and lets Binghe occasionally have his way with him he's 100% safe from all the bad things in PIDW by virtue of being the protagonist's woman! And when Bingge isn't around he can cultivate (cool!) and read his way through the extensive library (so cool!) and anything else his little shut in heart desires!
And ok yeah there's the, sigh, doing the wifely duties bit but he's wife like, 63 so it isn't happening often and besides, his lady body is clearly into Binghe, and he's a straight guy yeah but Binghe is Binghe everyone wants him! So he's willing enough.
So the Event finally happens and SY gets his world absolutely rocked by Bingge... And then when Bingge's about to get up and leave (he Does Not spend the night ever) his wife pulls him close. He thinks that she just wants to go again- which is weird enough, he always completely satisfies his wives- but she just cuddles up to him and plays with his hair and tells him what a good husband and man he is and then starts humming. And Bingge stays, it's...nice and he is tired, his wife is right he works so hard he does deserve to relax...
He wakes up in his wife's arms the next morning utterly bewildered. And then SY helps him bath and does his hair and tries to get him breakfast but he insists he's busy just to get away from her to get his head straight. SY doesn't press of course he just tells Bingge to eat something before he gets into any fights.
Bingge is sure this wife must want something... But a quick background check reminds him this wife is one of the ones he saved from a magic crystal, she has no family, they all died centuries ago... So his wife is not seeking any political gain...
He eventually just goes and asks her, and SY is like oh no I'm peachy! Husband could come with me to the library though if he's not busy? SY is looking for books on monsters!
Bingge is very quickly wife-beamed, which is convenient for him because he's already married to this wife. And SY has no idea it's happened. Well, the other wives are getting cattier the more often Bingge spends the night, but why would he want to be around them when their attitudes are so bad?? (There's been more than one assassination attempt that SY missed completely. Didn't even notice he was in danger.)
But there's a problem. This is not a clean transmigration. The longer SY is in Wife 63's body the more he realizes she's still here too, suppressed by him in her own mind! He isn't sure what to do about it, he can't talk to her directly and what he does get from her as she slowly wakes up and gets stronger is... Hostile to say the least.
SY tries to play it cool, he's fine everything is fine. But Bingge notices the changes, especially as the original wife gets strong enough to start taking partial control of the body back.
Eventually he does a medical check and Oh no! His favorite wife he was considering making his empress is possessed! She's being so so brave and trying to downplay her symptoms but he knows she's suffering.
Bingge arranges for an exorcism and SY goes along willingly. After all he is the bad guy here technically, and the invading spirit. Surely Binghe will be happier with his wife not controlled by a straight man! (I mean yeah the sex is fantastic but he can probably tell it's a little gay somehow!)
Still he's going to miss Binghe- assuming this exorcism doesn't just kill him- so before the ritual starts he makes sure to tell Binghe he loves him (totally platonically) and only wants him to be happy.
It takes Binghe five minutes post exorcism to figure out that he got it backwards. He wasn't saving his beloved wife from a ghost! He's cast out his beloved ghost in favor of some lady who's pissed he didn't realize she was possessed immediately!
He needs to get his perfect ghost wife husband ("the spirit I expelled was actually male " the exorcist says.) back! And find a body to put him in since Wife 63 is refusing to surrender her body again for some reason!
