can’t find it T-T

so i read a yaoi necrophilia manga a long time ago and i was hoping someone would recognize the plot i’m about to say and reply with the manga please. so basically a guy who looks like he’s too young for his age sneaks around in a graveyard until another guy catches him scolds the younger looking dude until the guy who works there get wacked in the head with a shovel. but we realize he’s actually a zombie... (i am not a pervert it’s just bothering me that i can’t figure out what it is ╥﹏╥)
