Dark possessive Caroline sbi

Tommy is a normal boy who moves with his parents Kristen and Philza and his older brothers Wilbur and techno into an old house for they're parents work.
His parents doesn't has much time for him bc of they're work and his brothers doing they're own think what they like. Tommy hates being neglect by them but he lives with that since he was 8.
BUT what happends when tommy finds a little door in his room behind the wallpaper, and feels like he's being watched, bc of his curiosity he's opening the door and going in.

Also tubbo and ranboo are gonna be here too but only a little bit bc it's an sbi fanfic but I will try to add them more ok.

Also this is my AU of Sbi Caroline so don't judge me if theres somthing different okay
