Inoue Azusa is an ordinary high school girl caught between two very different boys. Saito is strikingly handsome but has a terrible personality—he is rude, blunt, and seems to take pleasure in bothering Azusa. Despite his abrasive behavior, he has a principled side that begins to draw her in. Meanwhile, Hikaru, Azusa's classmate and the class president, is kind, reliable, and secretly in love with her. As Azusa navigates her growing feelings for the infuriating yet intriguing Saito, she also wrestles with the unexpected weight of Hikaru's confession. The story deepens into a love triangle that expands into a quadrangle when her best friend Tamami becomes involved, forcing Azusa to confront the difference between like and dislike, and the blurred line between the two. The narrative arcs follow Azusa through the turmoil of first love, the pressure of high school life, and the painful process of understanding her own heart and the hidden vulnerabilities of the people around her.
