This work is a “misaligned, heart-fluttering romantic comedy” centered on Amami Haru, an eccentric and handsome young man whose only best friend is an AI, and Karashima Naho, a work-driven woman employed at a game company.
One day, Naho bumps into Haru at a park and ends up spilling coffee all over the vintage clothes he is wearing. Unable to afford compensation, Naho agrees to Haru’s proposal to settle the matter with “30 homemade boxed lunches,” and the two enter into a strange contract.
Although Naho is thrown off by Haru’s unpredictable words and behavior, as they begin spending their 50-minute lunch breaks together, the distance between them gradually closes. However, Naho soon discovers Haru’s true identity: he is a game creator attracting attention from around the world. Moreover, the company he belongs to turns out to be a rival of Naho’s own company, forcing their relationship to become a secret that must be kept hidden.
