Help me find this yaoi pls?

the main couple were a serial killer who wore a bag as a mask (it has a hole for only 1 eye I think?) and his victim (well kinda???? Technically but likee) anyway this victim guy is blond I'm pretty sure? ALSO it's a manga I think and it's in black & white!
I'm pretty certain the serial killer had mother issues or something to do with his parents... The way the killer and the victim got together was by the victim witnessing the killer killing some people, he panicked and he just idk mumbled some shit to killer (something something I'm a fan of you, mr!!!! I love you;!! something????) and the killer fell in love w/ him like that.
Well that's all I remember, please help me if you can! Also da serial killer is da top and he had a crazy skinny cannibal friend who's a twink I'm certain....
