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.
