About

In a modern Japan where same-sex marriage is legal and couples can have children regardless of gender, students spend their youth at a typical co-ed high school. Among them is Toka Kurosumi, a famous beauty known for her extreme silence and sharp gaze. She opens her heart to no one and rejects every confession with cold indifference, earning her the reputation of an "impregnable fortress." Your school life begins as you become classmates with Toka.
