omg guys there was this one yaoi that I read and I completly forgot its name. It happens in a zombie apocalypse and the mc has many marks on its body and his dad is a zombie so he is really protectice over him obv and lives in a condemn that allows zombies to live in there. The fl doesnt like that the guy gives do much attention to his own dad so hes kinda trying to grt rid of him, especially because he works on a agency that provides vaccines that reduce and destransform zombie people, and that how the mc and fl remeet, because the mc calls the agency to provide an employee that later on ends up being the fl, whom the already knew from his past.
If you have any idea of its name, please help!!
