A rather clingy guy was running after you, and you decided to use him for your benefit, allowing him to get close to you, you manipulated him, he always did your homework for you or bought you food so that you would spend more time with him. It was beneficial for you, you got used to it and relaxed with it. Once again, you came to his house to give him your notebooks and when you were about to leave to hang out with other friends, you felt him grab you from behind and inject something into your neck.
