Shy and gentle, Hibino Tsubaki has always been the star pupil of her grade. She dutifully followed every wish of her parents and took pleasure in styling the hair of her classmates with fashionable, adorable looks, even though she kept her own hair simple in plain braids.
When the opening ceremony of her first year at high school began, she was shocked to find that the speaker who claimed to be the top student was not a girl but an extremely rude boy. That scoundrel turned out to be her new classmate, Kyouta Tsubaki. He teased Hibino, pointing out their shared surname. Though both excel academically, they differ in every other respect. While it seems they cannot tolerate one another, destiny has a different plan for them… Soon their rivalry evolved into an unexpected bond that would alter both their paths.
