Kyou, Koi wo Hajimemasu

Tsubaki enjoys styling her younger sister’s hair each morning but believes such looks don’t suit her. On the day of her high school’s opening ceremony, she fails to become the top student, a role that typically includes giving a speech. She ends up seated next to Kyouta, the actual top student among the first years, a notoriously rude boy. After Kyouta says something hurtful, Tsubaki retaliates by cutting his hair. Kyouta demands repayment "with her body," but Tsubaki instead fixes his hair, making it even shorter. In response, Kyouta unexpectedly kisses her and vows to make her his woman. The first volume includes a prologue titled "Koimonogatari e no Prologue."
