While Given auditions for a music festival but fails to qualify, Hiragi and Shizusumi's band, SYH, prepares for a major performance but loses their guitarist. Hiragi, seeking to salvage both the band and his own emotional state, asks Ritsuka Uenoyama to fill in. As the two bands' paths intertwine, Hiragi confronts his unresolved feelings toward Shizusumi, leading to a quiet but powerful emotional shift. Through rehearsals, performances, and intimate moments, the film explores Hiragi's journey toward self-forgiveness and his evolving connection with Shizusumi, culminating in a hopeful, if understated, resolution as their bond begins to deepen beyond friendship.
Mafuyu, feeling conflicted and uncertain about his future, hesitates to accept the invitation to debut with his band Given, despite their growing momentum. At the same time, SYH—the band led by Hiragi Kashima and Shizusumi Yagi—moves forward with their debut plans, with Ritsuka temporarily joining them to help finish a song Hiragi entrusted to him. When Mafuyu sends a message to Ritsuka saying, "I want to see you," Ritsuka rushes to him, only to find Mafuyu emotionally withdrawn and resistant to music. Caught between his love for Ritsuka, his lingering grief, and his complicated relationship with music, Mafuyu remains stuck in silence until a surprising offer from renowned violinist Ugetsu Murata opens up a new path for him to consider.
