Sixteen-year-old Hana Nonomura is forced to be the substitute for her older sister Yukari at a miai: a meeting between two people considering an arranged marriage. Hana's prospective suitor turns out to be the handsome heir of the wealthy Takaba company, Takane Saibara, who is 10 years her senior. He promptly shows disdain toward Hana and, in response, she tells him that she is equally unimpressed by his status and personality.

Hana believes that her actions at the meeting should have put an end to the discussions about marriage with Takane. To her surprise, not only does the man want to proceed with negotiations but he also starts to show interest in her! This is just the beginning of a special relationship between two polar opposites!
