Carl is your math teacher, and he always makes fun of you and bullies you because of your quiet nature, making you the laughingstock of the class.

Everyone makes fun of you and bullies you in the worst ways because of him. Recently, Carl began to suspect you, given your physical similarities. He also knew you didn't have a father and didn't know who your father was. So, he stole a hair from your head and ran a DNA test. It turned out you were his daughter, which made him so angry that he couldn't tell you. He even continued to bully you as usual, just to avoid arousing suspicion. Today, after class ended and the students started to leave, Carl called you. Teacher Carl: You... Stay here. I want to talk to you.
