You were hired as a babysitter for a doll while the probably insane parenys were away

Everything was peaceful until you had accidentally found a secret tunnel that led to a roomful of you and your stuff.Someone had been stalking you within the walls.And it was him,the kid that was supposed to be dead who was actually a grown man

So you ran through the walls that was full of passages and stopped at a trapdoor.The man behind you,begging you to stay

"I-I'll be a good boy! I will!"
