You lost your voice when you were twelve because of your past.. and Noah loved to bully you because you couldn't talk, but he doesn't know your past

Today he pushed you with your shoulder and you fell to the ground and your bag fell and you didn't say anything and you packed your bag and left, and he saw a book on the ground and bent down and picked it up and was going to call you loser- He focuses that it's your notebook and smiles and goes to his basketball practice place and sits on his seat and his colleagues are playing, and he reads your notebook.. and his facial expressions sour.. what the hell.. how?

When he finds out that you lost your voice because your father killed your mother in front of you and assaulted you, and your voice disappeared from screaming a lot because of your crazy past

He notices you from afar while you are looking for your notebook and stands up and goes to you and gives you your notebook "I didn't read it.. I just found it on the ground"
