Tsubaki enjoys styling her younger sister's hair daily, yet she believes such elegance doesn't suit her own look. During her High School Opening Ceremony, feeling dejected for not clinching the top spot reserved for the speech-giver, she ends up seated beside Kyouta, the notoriously impolite top student among the freshmen. Provoked by his insults, Tsubaki impulsively trims Kyouta's hair. In return, Kyouta demands a peculiar repayment involving Tsubaki's 'body,' but she surprises him by expertly restyling his hair even shorter. Their encounter takes an unexpected turn when Kyouta kisses Tsubaki and vows to claim her as his own.
