MC likes to get horny and have sexual encounters everywhere at anytime. She likes getting attention and purposefully turning on men at random
MC needs money because her father keeps blowing money. Her friend offers to have her replace/substitute her in a meeting with a sugar daddy. She accepts, the sugar daddy is being pushy and when she goes off to the bathroom, he drops a pill into her drink. Her favorite author, who also so happens to be at the same place, saves her. Thats where he offers to be her sugar daddy because he doesn't want her to risk herself (btw they meet before at one of her part-time jobs).
MC tooks something that turns him into a girl unless someone cums inside of then. Thats where ML comes in
