A badminton hopeful and a basketball star collide, sparking love, rivalry, and a national‑level showdown.

First‑year student Taiki Inomata spends his mornings at the high‑school gym, not just to sharpen his badminton swing but to catch glimpses of Chinatsu Kano, the charismatic senior who dominates the girls’ basketball court. While Chinatsu projects an icy, untouchable aura, Taiki’s quiet persistence gradually chips away at the distance between them, turning fleeting encounters into genuine moments of connection. Their budding friendship fuels both of their ambitions: Taiki’s drive to break into the varsity lineup and Chinatsu’s resolve to chase a national title after her family’s sudden overseas posting forces her to stay behind. When Chinatsu ends up living under the same roof as Taiki’s mother—thanks to a long‑standing family friendship—their lives intertwine in ways neither anticipated. Amid the cramped living quarters, Taiki vows to elevate his game alongside her, while his childhood friend and gymnast Hina Chouno offers unwavering support. Together, they navigate the pressures of elite school sports, the tangled emotions of a love polygon, and the relentless pursuit of a dream that could either bind them together or tear them apart.
