I absolutely get where people are coming from with Dom Mobei Jun in fics and it's often extremely good, but there is just so so much potential with Dom Shang Qinghua and Sub Mobei Jun.
I just really think they would be into the switch in their public-facing relationship dynamics for bedroom activities. The games they could play! Clever "lowly" servant Shang Qinghua pretending he's blackmailing or tricking Mobei Jun into servicing him for revenge, gloating about how he's got his king just where he wants him, getting to really cut loose on the degradation dirty talk (venting for all those years of holding back any kind of criticism out of fear for his life) while Mobei Jun gets some traditional demon courtship fixes out of the process, and also enjoys the opportunity to just completely turn off his brain and his vigilance around someone who he 100% trusts not to abuse the privilege.
Heck, their relationship didn't actually gain ground on physical intimacy until Shang Qinghua started finally cracking and losing his temper and demanding Mobei Jun respect him (and... call him 'daddy', of course...), and when Mobei Jun finally gets Shang Qinghua to tell him how to court him he's like "finally" and makes him the world's worst noodles about it. He's glad that Shang Qinghua is telling him what to do in order to please him! He wants that.
In conclusion, Mobei Jun would absolutely enjoy being bossed around and I think Shang Qinghua would equally enjoy ordering him to do various bedroom activities, in the most unrefined terms available, and being immediately served & obeyed.
