At the West Tokyo branch office of Pakupaku Confectionery, capable salarymen clinch successive business deals. However, nothing seems to go right for four of the people among the busy staff. Even though they always give it their best, they would fail and get scolded and have to start all over again. There is Yoko Wataru who is the one the other three would like to depend on because he is the most senior, but he is incompetent, has bad timing in everything and falters when he speaks; Miyata Toshiya often gets scolded due to his naivete and inability to read situations; Nikaido Takashi is the athletic sort, very diligent, tends to get extremely close to other people when talking and has a pretty quick temper; and Senga Kento who is stylish and good at his work, but is somewhat blur and oddly harsh towards females but lenient with males. The foursome grapple with the challenges which appear inside and outside the company although they are in danger of being laid off.
