Im trying to find a webtoon i read. Its about a gray haired boy thats a zombie and another boy from his class is a scientist sign in charge of looking after him and testing him. Where i left off at the mc (zombie boi) love interest moved back into his town after looking for him. It hints that they were in love with each other but im pretty sure it isnt tagged as an yaoi. Thanks for helping me out!!

Okay so In the very beginning it starts out as the mc doing a demon ritual well a demon comes and goes to grant his wish thinking that the high school boy would ask to get rid of his virginity or something else simple like that but instead he ask to eat the demon. So the goes on for a couple of weeks ratting the demon from the feet up. Eventually the kid gets bored and the demon convinced the kid to LITERALLY fuck his guts. The demon shows him some “more exciting” by cutting his throat open and have the kid fuck his throat. Anyway the demon likes how messed up and sadistic the kid is and plans to make him a demon (to which he’ll eventually surpass the demon he summoned to become a powerful demon) the first week the demon has his head attached to a dog’s body. He gets his human body and then is sent to work at a demon prostitution thing. The demon picks him back up because the kid apparently needs to be fucked up the ass to “get rid of his human smell” so the top prostitute fucks him and he has this really long dick (kinda looks like a elephant trunk lol). Anyway that’s all i really remember. I’d really like to find this manga because I love dark themed manga like this if anyone reading this would like to share more dark themed yaoi I’d really appreciate it!!
