Kanou from Okane ga Nai - rapey bugger with a predilection for a lover who looks like he is 10 and dresses him in oversized floofy clothes
http://www.mangago.zone/read-manga/if_you_hate_me_that_much/uu/if_you_hate_me_that_much-chapter-1 Soo hyeongjo. Really, he's just so selfish and shitty. All he did was to rape the uke and then poof. He's in LOVE. Bullshit.
Can't have that list be without the worst of the worst:
Yule from Hogu Hagyeongsu

I’m trying to make a list of the worst Semes in Yaoi manga.
These can be any type of Semes even Semes from Yaoi mangas that you like.
The only requirement is that they make you angry or frustrated with them. Or maybe they just creep you out.
Feel free to explain why they’re the worst!
