Two Empires, The Slave Of The Empire
Don't expect anything cute. The top keeps raping the bottom until they somehow fall for each other. Before they fall for each other the too treats him like shit, to the point where the bottom gets raped by someone else, only for the bottom to forgive him. I honestly wished he eloped with Christian, who's so much better than the top. Would not recommend except you really are bored. Oh also it's kinda pedo. The top is a pedo and the bottom was a pedo, though I suppose it was normal back then. Still disgusting.

This one has a good art style and even the story has potential but the constant non con was really off putting. Like I said the story is good but it felt rushed for only 10 chapters, it needed many more chapters to be enjoyed.

Shion (bottom) is definitely in love with Rui (top) but I honestly don't think Rui is actually in love with him, at least not at first. The mangaka made him say "I've loved you even before you turned into a girl" but huhh?? no you weren't, you were clearly having fun with your girls and showed no love for him whatsoever until he turned female. Read it for the smut but don't expect real love here
