Shen Qingqiu who, while Shang Qinghua is recovering from some random poisoning (that demon has already died at the hands of Mobei, don't worry), is forced to spend time with Mobei-jun.
At first it's tense. He arrives, a mandatory tea out of politeness. It's usually frozen. They don't have much to talk about or anything in common except their concern for Shang Qinghua.
Except they do have in common. At some point, perhaps, Shen Qingqiu mentions some rare beast, and Mobei-jun comments that he killed a couple of those. That leads to the first long conversation the two of you can have.
The next time, Mobei-jun brings back the beast's fangs. The two return to their conversation about monsters. Mobei-jun speaks little, concisely, but he talks about how to kill those beasts, the properties of their organs, the functioning of their poisons. Shen Qingqiu shares his bestiaries and provides additional information.
Then, even when Shang Qinghua improves, Shen Qingqiu usually takes advantage of the time when he has to stay in the northern palace with his husband to, well, expand his bestiary. Mobei-jun also seems to be passionate about flora that can kill, or anything huge and dangerous. Shen Qingqiu enjoys their conversations and learns to get more than just a few words out of Mobei-jun's sullen mouth.
Of course, he actually tells Shang Qinghua:
"When your husband isn't being monosyllabic, it's a good conversation" he says simply. "I didn't know he knew so much about flora, monsters and strange beasts. When I find a rare flower and can't remember its name, I'll ask Mobei, not you."
Shang Qinghua laughs a lot at that.
"Ah, I think that's because, well, you know, inspirations and all that..."
Shen Qingqiu looks at Shang Qinghua very curiously.
"Inspirations? You created your perfect husband from scratch. Who did you get your inspiration from, Airplane bro? Spill the tea, let's see the vicious tastes of this shameless author."
Shang Qinghua laughs a little foolishly.
"Well, you see, I had this classmate in college. A very rich guy" Shang Qinghua makes a funny face as he buries in the past. "He was cold and monosyllabic, even hostile to those who were rude, but hey, he could give you an infodumping of all the monsters in The Witcher without even doing research. I heard him do it once and, man, that guy was crazy" and Shang Qinghua continues talking while, as if by omen, Shen Qingqiu begins to feel a strange sensation of vertigo. "He was kind of cute, well, not exactly my fully type, he was very tall but lacked many muscles, but he had the biggest and prettiest resting bitch face I've ever seen on anyone even my king. He always wore all those fancy clothes that cost the same as my apartment rent, those silver accessories, rings, necklaces, bracelets... His hair was also kind of long, now that I think about it, and when he wore it down it was, god, a delight. I liked him a little. He was my college crush." and Shang Qinghua shrugs, laughing. His cheeks are red and Shen Qingqiu feels that his own ears are red, too. "Cucumber bro, it's actually a bit silly. I remember this boy's last name was also Shen."
That... That's the last straw.
"You-!" and Shen Qingqiu finds himself hitting him with the fan before he realizes it. "How-? What the hell!?"
"Ow, ow, OUCH, Cucumber bro!! What's going on?!"
Shen Qingqiu feels his face burning. His hands tremble over the fan. What the fuck!?
"... Bro?!"
"That classmate of yours" Shen Qingqiu hisses, just to confirm "His name was Shen Yuan?"
Shang Qinghua blinks, confused, recalling his thoughts. Suddenly, his entire face lights up with a wide smile.
"Oh, I forgot!! Yes, that was it!!" and his gaze becomes mischievous. "You met him, too?! He was a delicious little thing, honestly, a nice round butt, he... OUCH-"
"He was me" Shen Qingqiu hisses, opening his fan and hiding behind it. He wrinkles his nose in disgust. Of all the people in the world...!
Shang Qinghua gasps, looking like he was given some vital information. His face, contrary to what Shen Qingqiu expected, does not change into horror, but into mockery.
"Oh, bro" and starts laughing out loud "BRO"
"Damn fourth-rate author, what the hell is wrong with you!!!"
"Bro, BRO, I created a part of my husband based on you!! And you're married to my son self-inserted in a power fantasy!! It's like we're indirectly married!!"
"Fuck you!!"
"Ohh, how cute!! Do you want to jump to the honeymoon already?!"
"Get away!!"
Shen Qingqiu doesn't visit Shang Qinghua again for over a month. However, he does spend some time talking about monsters with Mobei-jun while his husband takes care of the demon court (in the time he would usually use to gossip and fool around with Shang Qinghua), it's just his thing.
