Pls help me find this

Ughhh idk it was about some kinda zombie apocalypse kinda thing where this bottom and his friend who likes him get trapped and there’s this hybrid top who falls for the bottom, the bottom and the friend try to escape and shit happens i don’t remember but the friend turns into a zombie/demon and the top and the friend disappear. Lots of grape later bottom escapes to a place where he finds the guy who has turned into the demon who he felt guilty for not saving initially and now is grapef by him too. Idk where the story is going but i wanna know what happens. This is a messy context but yeah
