Hey all. Hope everyone is safe and healthy. I’m looking for a manga that I was reading a while back. I never finished it and I cannot for the life of me remember the title. The manga is about a group of kids who murder the abusive dad of one of the kids. Years later, a mysterious person threatens to expose them for the murder. I think it ran to 80 something chapters?
Any help finding the manga would be appreciated

Thanks, and best
