Kazuyuki Yamamura works at a major advertising agency, and is the breadwinner of his family, which consists of himself, wife Miki, and daughter Rie. He purchases a house, and is proud of being at the pinnacle of his career.
Kazuyuki's neighbor, Yusuke Sugio, however, leads a completely different life. The breadwinner of his family is his wife Shoko, who runs her own company. Yusuke is a so-called "at-home dad", and because of this, Kazuyuki considers him miserable and helpless.
Suddenly one day, Kazuyuki is forced to quit his company. At the same time, his wife receives a call from her former employer saying he wants her to come back to work. Consequently, Kazuyuki has no other choice but to stay at home while Miki works. Kazuyuki reluctantly starts his new life as a household husband—the last thing he wanted to do.
