Mio Natsume serves as the story's leading heroine, sharing a middle school past with both Eita and Haruto. Consumed by university entrance preparations, she channels her energy into studying—partly as a shield against the unrequited feelings she has long harbored for Haruto. When Eita unexpectedly returns as a transfer student, the emotional walls she carefully constructed begin to crumble. Beneath her composed and self-assured exterior lies a girl of quiet vulnerability and clumsy affection, who ultimately rediscovers her true heart amid the pressures of exam season.
