In the spring, Ami (played by Matsui Airi) is an ordinary office lady. When she and her boyfriend were about to enter the marriage palace together, she was betrayed by her boyfriend. Ami has since lost confidence in marriage and love. Amid the increasing pressure from her family to get married, she decided to solve her lifelong event as soon as possible through blind dates. On the marriage and dating app, a man named Miura Manatsu (played by Itagaki Mizuo) attracted Ami's attention. Miura expressed his hope to find a woman who could marry him immediately. In this way, the two people who hit it off so hastily entered the palace of marriage hand in hand. However, what Ami didn't expect was that Miura actually worked in a different department of the same company as herself. In this way, the fact that the two were married became a secret that needed to be concealed from colleagues and superiors in the company.
