It has been two years since Sagenya Machi and Yashiro Hajime left Teiko Real Estate’s Shinjuku office. Sales at the office, which is now led by Fuse Makoto, have been sluggish because of the rise of a rival and the office is on the verge of closing down. Niwano Seiji visits Machi who has become the company president of Sanchi Real Estate to seek her help. However, he sees Machi and Yashiro standing alone on the beach and the baby in Machi’s arms. Despite his shock, Machi shows up at the brokerage sales department the next day to work part time for a limited duration, and brilliantly sells a house to a peculiar client in no time. The next day, Ichinose Sadao, a strange old man of leisure who is in the costume of the office’s mascot for promotional activities, sees Machi’s sales prowess at an event to sell a maisonette. He suddenly takes off his costume and declares that he is buying it. He claims that he has been checking out trustworthy real estate agents under the guise of his part-time work. He wants to buy a house that he can live together with his daughter and her family with whom he has broken off ties, and make peace. However, Machi rejects him for some reason. An angry Ichinose uses the office’s hopeless employee Shirasu Mika for some strategy. Meanwhile, a famous child star Hayama Ren visits the office with his father Tomoaki. With an insolent manner which is hard to imagine for a child, the boy finds fault with every property proposed by Niwano and the hapless Tomoaki just obeys his son. Then a destitute single mother searching for a modest home and a wealthy university student buying a house for her dog with her parents’ money come to the office too. Even the chief Adachi Makoto gets involved. Machi comes up with excellent solutions for them. What are the answers she sees through houses? And what is her relationship with Yashiro and the secret of the baby’s birth?
