Kei's secret is out: Houou High's chairman knows she's a girl! Desperate to keep girls out of his male-only school, Chairman Ooshima will stop at nothing to edge Kei out of Houou High. Kei's overprotective father is only too happy to agree, and gladly submits his daughter's withdrawal application. Kei always thought she'd be happy when the time came for her to jump back into a blissful life full of girls, and escape from her servitude to Yui, but a revelation about her past—and regarding Yui—has her asking: "Do I really want to leave Houou High?" In light of these revelations, Kei tries to help Yui confront his feelings toward his father, while she is forced to acknowledge her own feelings for her roommate. Now she must decide what she will do, whether it be challenging the system or returning to the comforts of her old life, to find happiness.
