A band-themed coming-of-age story
When the after-school chime rings, a quiet stillness gradually returns to the school building. However, the music room at the far end of the old school building is different. Gathered there are six famous high school students who all belong to the same light music club. Their personalities and musical tastes are all over the place. Yet, when they pick up their instruments and layer their sounds, they become one in a mysterious way. —Youth is surely just a fleeting moment. School festivals, live shows, exams, and future career paths. Laughing over silly things, and fighting over trivial matters. In that daily life, their feelings slowly begin to change. It wasn't just music; a "love" they couldn't tell anyone about was starting to sprout. This is a story of six high school students playing out a noisy, dazzling tale of love. Today, after school, our music begins again.
