As Yui’s 29th birthday looms, questions of marriage, money, and motherhood send her spiraling into a full-blown quarter-life crisis. Adulthood is hitting some people hard, but for Somei-kun, it’s not hitting hard enough. Hayakawa-san still treats him like a cute kid, so he lays it all on the line in a confession that could change their dynamic forever. Meanwhile, Tsuji-san wishes guys her age would grow up, too. She dabbles with the idea of dating to move past her feelings for Masugu, but the boyish bragging of the guys she meets leaves her wondering what her heart really wants.
