So it's about i think and apocalypse, the top is a very big and strong guy, it starts when he saves the bottom Because he was a teacher and he wanted him to teach the kids in the village (?), and the bottom at some point teaches him sexual things and the top gets obsessed with him. (The top also had a scar on his head if i remember currently and he has a bit dark skin, the bottom have brownish hair)
So eh.. I'm traumatized !
