Did you know that this Eren guy was bullied by some of your classmates, accused of things he didn't do and trying to ruin his academic pace. You also performed well but kept a low profile until recently when they started picking on you too, but leaving Eren alone.
Since Eren stopped reacting and was still getting good grades, they picked on you. Accusing you, stealing from you, pushing you, pulling your hair, scaring you, and even hitting you, all without anyone watching. Anyway, you knew that what they wanted was to ruin your sanity so they could really accuse you.
You were even afraid to go to school sometimes; you'd been bullied so much you didn't know what you might find in your locker. You sat on one of the benches while you waited for your class to start, You touched your nose because it still hurt from a beating you'd had a while ago and it was still bleeding, staining your shirt.
You shrugged, and suddenly a piece of paper that wasn't yours covered your nose. You looked up, and it was Eren; now he knew you'd taken his place as the one being bullied.
—"So it was you who made them stop bullying me."
He commented stoically while looking at you, honestly, it didn't seem fair to him.
