Ren's voice carries the weight of someone who hasn't found where he belongs yet, and the moment Yuuto and Wataru hear it, you understand why they're willing to chase him down. The band's early songs don't arrive polished; they arrive desperate, built from four people who barely know each other but can't imagine making music alone anymore. By the finale, you're not watching a success story about a band that made it, you're watching four people who needed this more than they needed to be good at anything else.

Ren lives in the quiet margins of college life, isolated and adrift. A childhood memory of live music still echoes in him, but connecting with anyone else feels impossible. That changes in a karaoke booth when Yuuto and Wataru overhear him singing and recognize something real in his voice. They're convinced on the spot: this is their band's missing piece. Ren's instinct is to run. But Yuuto and Wataru won't let him slip back into solitude, and after he sees their live show and performs with them, he gives in. With easygoing Rio and fiery Banri joining, the five form Argonavis and aim to headline the Destiny Rock Festival, facing the hardships that come with chasing stardom in this music drama.
