The old man marries a wife for his son with a different purpose.

Ozawa, the president of a company, is worried that his wayward son shows no signs of getting married, and plans an arranged marriage between him and Rio, the daughter of a business partner. However, this arrangement is not for my son, but for my own desire. Ozawa forces her to admit her relationship with his son and forbids any sexual relations before her wedding day a year later. And a year later, I order my son to go on a business trip five days after their failed wedding night.
