The Kirishima Thing (2012) on Netflix

Plot summary

Kirishima, a popular second-year, leads the volleyball team and dates one of the school's most popular girls. Then he stops showing up, and word goes around that he is quitting the club. That same day the film club is teased at morning assembly over the title of a romance their teacher made them film, and the members set out to shoot a zombie movie instead. Their head, Maeda, meets Kasumi of the badminton club, who treats him with respect and asks about his zombie movie. The brass band's Sawashima has a crush on Kirishima's friend Hiroki and plays her saxophone nearby for him to notice. With Kirishima absent, the smaller Koizumi becomes the volleyball team's libero, while Mika sympathizes with him over Kubo's temper.
