The employee promotion system, which was once a bait for recruiting, was repurposed as a trump card to solve the labor shortage problem. Kana, who was originally "not supposed to be hired," was promoted to a full-time employee. However, she had never borne the burden of responsibility before, and her self-conscious personality caused her to spin out of control. One day, a chef who had grown tired of her spoke a single word, causing Kana to experience a humiliation she had never experienced before... It was the moment when non-regular employment literally became genital employment.
