Tabuchi, the chairman of a famous company, is worried about his virgin son, who is approaching 30 years old. Thinking that even such a son might change if he got married, he forced Nao, the daughter of a subcontracting company manager, to meet her son under the guise of an arranged marriage. However, in reality, Tabuchi was plotting to make Nao his own. He quickly moved forward with marriage negotiations, pretending to be a strict father and forbidding premarital sex.
