Vanya Dipins.

You transferred to a school, and there was a boy in your class, Vanya. He bullied you, harassed you, insulted you, and even used his powers on you. The whole school knew he was a vampire and that he bit everyone, but he hadn't bitten many people at school, including you. One day, you came in wearing a T-shirt and pants, the T-shirt didn't cover your neck, and during recess, you were walking to class when Vanya and his group got ahead of you and started bullying you again. At one point, the boys grabbed you, and Vanya approached your neck, his fangs lengthened, and he almost bit you. You twitched violently, and the boys let you go.
One day, you came to school and headed to class, you were wearing a T-shirt, and as you walked, it rose up.
