Boku no Tsuma to Kekkon Shite Kudasai

45-year-old Mimura Shuji is a man who loves making people laugh more than anything else. A staff of a TV station, he has lived a life dedicated to directing variety programmes. He was recently transferred from programme production to sales. Even so, he works with a smile every day. But one day, Mimura is summoned by the hospital where he had undergone a comprehensive medical examination. He is suddenly diagnosed with pancreatic cancer and is given six months to live. He hides his illness from his wife, Ayako, and puts on a brave face. However, he wonders what a very ordinary salaryman like himself with not much savings and a housing loan can do so that Ayako and their son will keep on smiling. He hits upon the idea of searching for someone who can safeguard his own family on his behalf. Gambling all that he has left of his life, he starts this absurd yet loving scheme to search for his wife’s new marriage partner.
