音楽室は秘密基地
A group of students gathers in their school's music room after class, turning it into their own secret base. They play instruments, sing, and share moments of friendship and creativity, finding a sense of belonging away from the pressures of daily life.
As they spend more time together, the music room becomes a sanctuary where they can express themselves freely. However, the arrival of a new challenge threatens to disrupt their peaceful haven, forcing them to confront what truly matters to them.
