Spica wo Tsukamaete

A third-year high school student named Nekozuka Serina focuses on earning a scholarship, but her appearance often violates the school's dress code. Tachibana Reiko, a member of the disciplinary committee, frequently enforces these rules against her. Reiko also consistently outperforms Serina in both academics and sports. One afternoon, Serina witnesses Reiko meeting a mysterious woman after school and entering a love hotel. The two now share a secret that could change their relationship.
