I can't really remember the story that well but the uke is supposedly meant to start working at his father's company and I think the company sold sex toys (it might have also been a love hotel), but he didn't know this and so the seme, who is one of the workers there, said he should test the products and they end up having sex

Does anyone have any historical yaoi reqs where the emperor is the uke and the minister/servant is the seme?
Bonus points if it's toxic lmao
well, it's a bit complicated in this one: https://www.mangago.me/read-manga/feng_yu_jiu_tian/
Oooo the description seems interesting!! Thank you :D
sure :) it's unfortunately unfinished, and even though there's a webnovel, it's a bit different (I personally did not enjoy the novel version). I read it many years ago, and the artstyle stuck with me ^^
