Honestly, this story should have been a shounen ai with smut for the side stories. After season one all they do is fuck and speed through plot important events and then those events are end abruptly because they go off to fuck (like most recent ch 111). It'd be more interesting if their actions were more thought out instead of "oops pheromones now x more amount of people know Prince is an omega". And also there are plots that seemed important that just get cut off and ignored?? What about that omega slave ring they mentioned and hasn't come up since, or those people Ettiene hired and was tracking down, there are too many plot holes
there was one where the uke's in love with his best friend and then an incubus shows up with and teases him with his pet tentacle monster if you find it thanks!
I'm really unsure about this, but maybe this one?

If not, you might want to look through the incubus tag to see if you can find it.
Honestly whole story pissed me off because it was so inconsistent with how season 1 started and I still hate how the empress had more character than ml and mc. And Rishard just pisses me off to no end, like you started some of these issues and then acted like it was because of other people and that he was so needed to keep Etienne safe even though you were the reason that so many other people found out about his secret. Also the abrupt ending? What the hell, there was barely any resolve to the many random side plots the author added. This is a good read if you just want to see two main characters kiss but not if you like to pay attention to world building
