Kinoshita Kazuya is a university student. Indecisive and soft, so as not to feel awkward, often deceives others, bypassing sharp corners in communication.
Kazuya is not popular with the opposite sex, but he had a girlfriend, Mami Nanami. It was the first experience in a romantic relationship, which lasted only a month, after which Nanami left him.
Kazuya is emotionally traumatized by the breakup, and in order to heal his broken heart, he orders a girl from an escort service.
The choice fell on Mizuhara Chizuru. She is beautiful, witty, attentive, and does her job well as a hired girl, but Kazuyu sometimes gets nervous in her presence for some reason.
One day, succumbing to an emotional impulse, Kazuya declares her his girlfriend.
Based on the 2017 manga of the same name, by Miyajima Reiji.
