Huli Jing Shen Yuan meeting Shang Qinghua in the northern palace when his clan is speaking about trade routes
He looks nearly 1:1 identical to Shen Qingqiu, but he wears dark robes and glasses while proudly sporting his twin tails, ears, and demon mark, and that catches Shang Qinghua off guard so he goes to speak with him.
It's revealed that, actually, this demon was once a human when he was a child, but he was experimented on heavily by demonic cultivators and is now a fully fledged demon because of it.
They realize they're both transmigrators and get to know each other, and after a while start to fall for one another.
It takes. A WHILE for Shen Yuan to realize his feelings. But he does, eventually. It takes a trip to Madam Meiyin and him being incessently teased by the succubi there for him to realize his feelings.
So the two eventually reveal feelings, and start courting in secret.
And then Shang Qinghua finds something NEW out one night while they're drinking.
While Shang Qinghua has his fingers running through Shen Yuan's tail fur, Shen Yuan reminices about his childhood on the streets, and about his twin brother.
His twin brother Shen Jiu.
Shang Qinghua is shocked. He definetly didn't write this, but he also didn't write Shen Yuan at all. Of course his lucky boyfriend got to be a very important custom made character.
"What-?" Shen Yuan shoots up, looking at Shang Qinghua. "Where? Take me to him." He grabs the front of his robes and shakes him.
"Wait- We have to plan this! And- you aren't going to be happy, baobei..."
"Why...?" Shen Yuan grows worried
"He's... Shen Jiu became Shen Qingqiu. And Yue Qi became Yue Qingyuan."
After a while of disussion and planning, Shang Qinghua manages to convince Shen Qingqiu to come with him, alone, on an impromptu mission. It took a lot of work, but he managed.
"Shen-Shixiong, this shidi is sure you're wondering what's so important... But I have someone you need to meet."
"Who could be so important that you interupt this masters-" He trails off as he hears rustling coming from the bushes, and a fox with three tails slips out and stares at Shen Qingqiu for a moment.
Shen Qingqiu is about to pull out his sword, able to tell this is a demon immediately, when the fox transforms into... Into...
"Jiu-di...? Is it really you...?" The ears on his head twitch with interest, and Shen Qingqiu feels his throat dry.
"Yuan-ge...?" The twins stare at one another, both clearly suspicious, before Shen Yuan spoke up.
"... No can no bb." A phrase Shen Yuan introduced to Shen Qingqiu as a child, in case they ever got seperated. A phrase to call in a crowd to find the other... Or in a case like this.
Their reunion is... A bit messy. There are tears. Shang Qinghua is threatened when Shen Qingqiu finds out they've been courting.
"What do you mean you've been courting a demon behind the sects back-!?"
"I mean- To be fair- It's A-Yuan, I don't think he could exactly be dangerous." "How dare you call him so familiarly-"
"Tell that to the demons I saved you from Hua-ge." He can't, any demons he's saved Shang Qinghua from are dead
