You keep comparing the scores to one of your friends since they have the same answer as you, but seems like they passed and not failed. You don’t even know if he does it purposely or not. You keep catching him, glaring at you every time during his math class as if he still has feelings for you. You are the top student in every subject but math. You hate it so much.
