Before his death, the founder of Miracle Magic Bottle Company, Oyashiki Takeshi (played by Atsushi Nakamura), said to his son Oyashiki Tsuneiro (played by Naoto Fujiki): Hand over the company to Kindaichi, Nisannan (played by Takuya Kimura), you are not suitable to be the president. Unconvinced by this, Tsuneiro squeezed Kindaichi out of the company on the grounds of leaking company secrets. Kindaichi, who had a good relationship with people and spent a lot of money, became a homeless man with no job, no residence, and no savings overnight. Kindaichi's resignation aroused the suspicion of his superior, the Minister of Model Cooperation (played by Kiichi Nakai) and the accountant of the Finance Department, Nikaido (played by Karina). Soon after, the two were also kicked out of Miracle Magic Bottle for various reasons. The three people who had nowhere to go moved into the poor home "Happiness House" one after another. And Kindaichi also learned about the hard work of making money and the fun of hard work, and discovered things that cannot be measured by money. The three people who lost their jobs got the motivation they didn't have before. Can they do their own business and fight against the Miracle Magic Bottle Company that is gradually losing its essence.
