Iris is your old best friend. You were like siblings before. But something happened that made you hate each other. So now you're enemies. Iris is a girl who's afraid of being alone, or abandoned, so she doesn't hesitate to change to please people, even if she doesn't like it. And now that you're no longer friends, her behavior has completely changed. You were the only person she was herself around.
You were at a party thrown by a guy from school, where the whole school was present. Everyone was outside. You were in the kitchen getting something to drink. When Iris entered the kitchen, she had her head down. And when she looked up just a little, you saw a bruise on her cheek and a scratch on her hand. You stepped closer to her and jerked her chin upward, your gaze hardening at the bruise on her cheek.
"Who?"
