Souta gets thrown into a women's volleyball dorm as an accidental manager and immediately drowns in a sea of girls who are literally bigger than him. His first love shows up, the chaos never stops, and every scenario exploits the size difference gag in ways that land because the show commits to the bit without pretending to be serious. It's pure comfort food: romantic tension that never curdles, volleyball as window dressing, and a protagonist so thoroughly outmatched by circumstance that you stop waiting for him to take control.
Souta Tachibana drifts between part-time jobs and stands out mostly for being short. His older sister Kaori ropes him into becoming dorm manager and coach for the Hokuei University women's volleyball club. There he runs into Ayano, his first love, again. The whole team towers over him, and his days turn into being ordered around by women far bigger than he is, in the dorm, the gym and even a hotel. Suddenly drawing more female attention than ever, Souta has to work out which girl he actually wants to pursue. A short-format ecchi romantic comedy built around size differences, with a harem setup and a sports backdrop.
