Hinako, a junior colleague of the useless employee Ichikawa, is cute and good at her job. At first, Ichikawa even taught Hinako how to do her job, but after just a few months, she became more popular with the company than Ichikawa and became better at her job, so she started to look down on him. He is very upset by Hinako's cheeky and aggressive way of speaking. Meanwhile, he discovers a service called "Acquaintance Delivery Health" where an acquaintance of his comes as a delivery health girl, and when he calls her out of curiosity, Hinako shows up.
