Yuzu Aihara, a fashionable, spontaneous and fun-loving city-girl, transfers to a new neighborhood and high-school after the remarriage of her mother. More preoccupied with boys and shopping than studying, Yuzu struggles to fit in at the conservative girls' school and frequently clashes with the student council—specifically Mei Aihara, the hard-working, beautiful but cold student council president. As it turns out, Mei happens to be Yuzu's new step-sister and
Yuzu finds herself having to share a bedroom with a girl she absolutely can't stand, yet can't get out of her head. The series follows the evolution of the relationship between the two girls, with the animosity slowly lessening as the two begin to learn more about each other and confusion growing as Yuzu discovers that she is starting to develop romantic feelings for her new sibling.
Yuzu is named after a citrus fruit and plant originating in East Asia. It is believed to be a hybrid of sour mandarin and Ichang papeda. Leaves are notable for a large petiole, resembling those of the related kaffir lime and ichang papeda, and are heavily scented, which relates to her infatuation with Mei's scent in chapter 1.
They also eventually ripen to an orange colour, which links to the characterization of Yuzu Aihara's hair. The fruit may also be cut in half, allowing the citrus juice to mingle with the bathwater. The yuzu bath, known commonly as yuzuyu, but also as yuzuburo, is said to guard against colds, treat the roughness of skin, warm the body, and relax the mind, which is why Mei constantly refers to Yuzu's body heat, as well as why there are multiple bathing scenes of Yuzu in the manga.
