In the eyes of employees, the head of personnel department, Onizuka Taro (played by Osugi Ren), is a man with a harsh and unsmiling personality. For this iron-faced boss, everyone's feelings are not so much respect as fear. Some even take advantage of various opportunities to do some unethical pranks on Onizuka, and Onizuka always silently bears these slanders. By chance, Onizuka met a cat. The cuteness of the cat touched Onizuka's heart, but thinking that he had sternly rejected his daughter's request to keep a cat not long ago, he had to give up the idea of taking the cat home. In desperation, Onizuka could only keep the cat in the staff dormitory. The warm story that happened in this small world became a secret kept by Onizuka and the cat. And Onizuka's colleagues and family found that this former "robot" gradually became gentle.
