He's a nice guy, but way too plain... That's Fukusuke Mogi, who secretly admires Kureha Yua, the most beautiful girl in the class. However, the one rumored to be with Yua is his best friend, Fujisaki Yusei, the ace of the basketball team. Feeling down about being a "mob character" overshadowed by his best friend, Fukusuke discovers another super cute girl who's hidden in Yua's shadow and doesn't stand out—Usuba Amari! "W-Would you... be my friend?" Sharing similar circumstances, Fukusuke and Amari decide to practice "becoming normal" together—what could possibly happen next?
