Tied by the red ribbon

Hiii! Just a quick note before the description:

This is a project that I've been working on since I was 9, and I'm now 15. Every year I write on this story, either if it's much or very little, to see my development. I know what you must be thinking. "A 9 year olds story must be so bad", but I've ALWAYS loved writing stories, so it's not bad!

Peter is an eleven year old boy who gets abducted on his way to school. He gets taken to a big basement where he meets other kids, he gets attached to a girl. Together they manage to escape...except for one. All that remains is a red ribbon that Peter holds on to. He is a smart boy and never gives on finding the one remaining, even when the police gives up. After the victims gets home to their families, they suffer from their traumas. What happens to the one that's still missing?
