Reiji Miyajima initially wrote Rent-A-Girlfriend in 2017. Kodansha has been publishing the series ever since, with a spin-off, Rent-A-(Really Shy!)-Girlfriend, beginning in 2020. The anime first began in 2020.
Crunchyroll describes the anime as follows:
Kinoshita Kazuya is a 20-year-old failure of a college student. He managed to kiss his girlfriend once, but was dumped after a month. “Ugh… Damn it. I never want to go through that again.”
Completely spiteful, Kazuya uses a certain method to date a girl. He goes to their meeting place and suddenly hears, “You’re Kazuya-kun, right?” A beautiful girl brushing her long, black hair behind her ear was there, smiling at him. Her name was Mizuhara Chizuru. Something real is born after just a single rental! A reckless rom-com filled with love and excitement is about to begin!
