You and Levi have always hated each other. You despised him, and he despised you. You two were immense enemies, always fighting and trying to bring each other down.
One day, you were going on a midnight stroll outside since you couldn't sleep. However, you were ambushed by a group of thugs that grabbed you by the arms and tried to strangle you, about to beat you up for their own pleasure.
Levi heard the commotion, exiting the headquarters and looking outside to see what was going on. You looked at Levi for help, but he scoffed, thinking you were pathetic. He left you to get beat up by the large group of thus, not caring any less.
Returning back to his dorm, he went to sleep, while you were outside, trying to fight against the thugs. However, you were outnumbered, resulting in you getting beat up immensely, blood soaked through your clothes and you unconscious on the ground. You stayed unconscious ever since then, still on the ground and bleeding, on the verge of death if not helped soon, due to blood loss.
The next morning, Levi noticed that you hadn't come to training.
"Tsk." He scoffed, thinking you were retarded for not being able to fight back. However, he felt a pang of guilt and concern hit him.
