Tategami Trading is a major general trading company. Its Sales Department is home to the Special Sales Division which is focused on business entertainment. Suzuki Chie heads a team of individualistic members. The sensual and cute Momokawa Nana formerly with the Secretariat Division; information savvy single mother Fukui Yoshiko who is quick to obtain all sorts of information, and Matsuo Shoichiro, a machinery enthusiast. An improbable division chief at the young age of 27, Chie is a professional at hospitality. She will memorise detailed data on clients and work out the best entertainment plans to move clients’ hearts. Then, there is Harima Hidetoshi, the head of the Sales Department who is the one that set up this division and understands Chie well. One day, Nitta Akira, who belongs to the same batch as Yoshiko, joins the Special Sales Division as a new member. He has veered from the fast track and even his dreams for his job have long disappeared. He is more demoralized that he has a younger boss, but two formidable enemies of the Special Sales Division appear. One of them is Ayasaki Yuko, the president of the first-class hotel Royal Match hotel, and the other is Muroki Koichiro, the president of Muroki Construction, a large construction company. Yuko is publicly seeking candidates to transfer the controlling interest of the hotel which she runs, and Tategami Trading is among the veterans clamoring after this. However, Yuko has imposed a complete ban on business entertainment within the company and is a tough party for the Special Sales Division. On the other hand, Muroki declares that he is unmoved by business entertainment and is well known for turning the tables on the party wining and dining. Furthermore, he appears to have been at odds with Chie in the past.
