Tojima, who works at a black company, gets yelled at by his boss Sasaki for unreasonable reasons every time. The main reason is Akane, the new employee assigned to the same department this term. She has charm and an amazing ass but can't do her job at all. Akane's educator, Fujita, had to take the blame for all of Akane's mistakes and was getting irritated. One day, the two ended up working late alone, and Fujita's stress exploded. Then, Fujita lunged at Akane's ass.
