复仇Yui Tsukino (Kimito Ayumi) is a salesperson of the nutritional drink "Riflet", and while working as a so-called refredi who delivers products to homes and workplaces, at night, he attends night college and learns French while saving money for study abroad. Was there. Although Yui had a faint thought at the exit of the branch manager, he learned that the company was in danger of survival due to poor sales, and he struggled with the lone army. However, the companies I visited to expand the sales channels were sexually harassed and could not easily increase sales. Meanwhile, I visited Noriko (Reina Kiyomoto), who was a senior and was married to the president of the business partner, and had a consultation.
