Homeless/No Home
So the black hair guy can see ghosts but it's meaningless in the story, the house isn't haunted (probably) and they never talk about the scary things in the house again (like the basement, the dolls, the fingers, etc.). It's just a slice of life about growing up (kind of) and living together, what home is, those kind of things.

Thought about the theory of twins but holy cow twist and turn everywhere. But what they did was awful, for 5 years they played with her. Crazy. And boy, the mother and the neighboor knew ? Just not her ? Poor her. I suspected she killed the wrong one when he got angry/jealous when she left the house + when he said he finished the kill, but still was surprised by the end.
