Remember Me, Please

Y/N L/N was one of the normal kids at school, that was until his "accident" where people started to not even see him, he was a popstar that was forgotten after he started to settle down and start school, he's gotten very depressed recently and he can't find any hope, then he finds one school mate that had the same struggles as him. Y/N also struggles with ADHD which is why he tries to keep away from people, but he got a big break with a record company that made him famous after hearing him sing for a school talent show.
