Kimi no Oto ga Nari Yamanai.

In his quiet rural town, Sanjou is known as the effortlessly popular guy who always seems to win over the girls. Yet beneath his charming exterior lies a passion he keeps entirely to himself: an intense love for techno music. With no one in his small community sharing his enthusiasm, he has never had the chance to talk about his favorite hobby. Everything changes when he discovers that his favorite DJ is scheduled to perform at a nearby venue. Desperate to experience the live set, Sanjou uses a fake ID to sneak into the club, expecting nothing more than a night of anonymous excitement. Instead, he is met with a shocking revelation. Standing behind the turntables, commanding the crowd as the DJ, is none other than his own classmate, Igarashi. The dark-eyed boy Sanjou sits next to every day harbors a secret life just as hidden as his own. Suddenly, the familiar boundaries of their classroom dissolve into a pulsing sanctuary of sound. Surrounded by heavy beats and flashing lights, Sanjou finds himself completely overwhelmed, his body surrendering to the intoxicating rhythms spun by the unexpected artist standing right before him.
