Shishi Mo Kobamazu
What a surprise! Despite the obvious deviation with consent issues at the beginning and communication problems, this is one of the most realistic depictions of a dom/sub relationship I've seen in a while. This is something that is actually difficult to convey and the mangaka here did it beautifully. It makes a nice change.
As You Wish (Seoho)
So close to perfect. Except they flubbed the landing. Definitely worth reading though. I loved the story.
From Dusk Till Dawn
The Pawn's Revenge
I love this. It's filthy. Gritty and a bit sleazy. Uke is a prostitute. Seme is a murderer. Both are fucked in the head. For people concerned, it's nothing like Killing Stalking. The couple genuinely develop feelings for each other. They have an equal amount of power in the relationship. But they are definitely not mentally stable. The seme enjoys killing despite not doing it for pleasure. The uke has yandere traits. TW: Dub Con. I would say if rape is a trigger avoid this just to be safe.
