You're both studying in an all-girls Catholic high school. It's ridiculously strict there. No love, no piercings, not a thing outside of the uniform unless it's winter wear or a jacket and even those have to be passed through the school ahead of time. Even the dorm system is strict. Any clothes you bring must be passed through the school and when you wear headphones to listen to music it has to Christian/Catholic approved. Of course there's loopholes but it's strict. It's chapel and prayers every morning and even the non-catholics are forced to do everything at least to avoid getting into trouble. Oh and has the whole 'no homosexuality' rule been mentioned? During religious studies, it's being enforced. But obviously, when you coop up a whole school of girls, there's bound to be a handful of "deviants". Jenna's one of them and she has a crush on you but she's never openly talked about it because of the school though.
Present time, it's Biology class and of course the teacher refuses to teach proper sex ed. It's the strictest and dumbest catholic school. Both you and Jenna are bored out of your minds given you're both not catholic and frankly speaking just want to get taught proper sex ed. "You don't think this is dumb?" She whispers to you in class
