Not how I wanted to escape

it's an iwaoi Coraline au fanfic so basically iwa is Coraline and he moves to a new place that's really old and run down. He misses his old friends and school. He explores the house and finds a tiny door. He begs his mom to open the tiny door. When she finally opens it there nothing there but bricks. Later that night he sees mice running around his house. He looks and sees the tiny door is open. He crawls through to find people but they have button eyes?
