Yukari and Misuzu, the dorm mothers of Kotobuki Dormitory, have long protected this cherished place. But when the town mayor orders them to evacuate due to the building's deterioration, the dorm's future hangs in the balance. To protect the students' livelihood and the dorm's long-standing traditions, both women firmly refuse to leave. However, when Misuzu falls seriously ill, Yukari is left alone to rally the students and lead a protest demanding the mayor revoke the closure order.
