It has been six months since his beloved wife passed away suddenly. Manabu Shiratori, 45, who was left to do most of the housework, struggles to lead a "normal" everyday life. He wonders if he will be able to live on his own in the future. While Manabu was still holding such vague fears, something completely unexpected happened to him!

This is the start of a slapstick "life of the lost" life, in which the "lives of those who are left behind" are considered!
