The Boy of Pen and Paper ( OP!MReader X bnha)

(Y/N) was never a kid with friends. Never a kid with hopes. Never a kid with dreams. All he was, was darkness and sadness. He often tried to summon demons, just so that he could have someone, or someTHING, to talk to. On one fateful night his summon worked... extraordinarily, though it wasn't a big demon, it was a powerful one, a damn powerful one at that. The demon, was but a child. (Y/N) decided to take it in. What he gets from it, will shock you...🤯🤯🤯
