Adrian

An accident left you with memory loss. A friend who came to visit you after you were discharged told you about what happened before the incident.
You hated school because you were bullied, beaten, and humiliated. The instigator was your classmate Adrian. No one knew the exact reason why he treated you the way he did. After all, he was quite loyal to everyone else.
"You never gave a reason, although everyone knew that something happened between you," your friend said.
You returned to school with a sense of trepidation. You knew what to expect, which only increased your anxiety.
You didn't remember your class. Your friend walked you to your seat. You caught whispers and sidelong glances as you found yourself surrounded by your classmates. You sat down and started getting your things.
"So it's true? Have you forgotten everything?" a mocking voice came from behind you. You turned around. And even though you didn't recognize the guy in front of you, your whole body cringed. Andrin smiled. He lifted you up and pulled your hair back. "Well, then, I'll remind you how much fun we had."
Fear momentarily paralyzed you, but the next moment, fear gave way to anger. A hard, heavy textbook found itself in your hands. And you hit Adrian in the face with it.
A scarlet mark blossomed on Adrian's cheek. He bit his lip, smiled, and looked at you.

• Oh, you've grown claws?
