Two different persons meet in an arranged engagement. What would become of them?
Touko was brought to the house of Rokuonji following the will of her grandfather, Eikichi, that she would have to be engaged to the grandchildren of Rokuonji family. The girl was also threatened that her village would turn into a water dam if she refused to come. Touko agreed, and because Rokuonji family had two grandchildren, Touko's life as the fiance of both Rokuonji Nagi and Rokuonji Kaze started.
When they met for the first time at Rokuonji's mansion, Nagi didn't show any interest at all in this engagement thing. He did any orders his grandmother told him to do, including kissing her right in front of the audience, without any care. He also thought of Touko as too unsophisticated. Touko didn't like Nagi either. She found out that Nagi was quite a playboy. He had lots of fans, but never really regarded them as anything. He was often seen with other girls as well.
After several "love trials", she learned more about Nagi and Kaze, and started to like them more. She still couldn't choose between Nagi and Kaze when the deciding time had come, so both left her to gave her some time to decide which one she would choose as her husband.
Unfortunately, due to a mistake, their engagement was canceled. Nagi and Kaze got a new fiance and Touko was put in position as a maid. She was tortured to look at the two boys growing close to the new girls. Yet, their feelings stayed the same. After she refused Kaze's proposal to marry him, she was shocked with the news that Nagi agreed to marry his new fiance. It turned out that he did it to give Touko back the right upon her village. At last both confessed their feelings and got married shortly after.
Nagi and Touko have similar characteristics. They pretend not to care in the outside while they actually do inside. It's clear when Touko decided to take care of the sick Nagi and Touko; when Nagi refused to chase after Touko when she couldn't choose between him or Kaze yet; or when he returned the village's deed to Touko in return for marrying his new fiance. Touko is a carefree and 'wild' girl, living close to nature at her village. Nagi too, has been the rebellious son, going out and play with girls before. Both learned how to control their ego when they met and eventually fell in love with another. From the extra story, it's shown that their stubborn heads brought trouble even to a small problem, though eventually they managed to return to peace after a talk to clear out the confusion. It seems like they would get lots of bumps along the way of their marriage, but as long as their love for each other stays true they would be able to overcome anything.
