Forgot serial name can you

I have watched a series on netflix and would like to watch it again now.It's about a group of children who have to find out a secret so that a ghost can continue to live in peace and it works and in the end it turns out that one of the kids too is a ghost

So in my opinion, it could be AnoHana. But it depends, AnoHana is an anime, but it's about the same thing

No that's not it
