Die-hard otaku Tomoya Aki never imagined himself falling for a girl in real life until one of his spring breaks, when he experienced a picturesque encounter with a mysterious beauty. Reminiscing about the brief yet enchanting event, he decides to produce a bishoujo game—a game focused on attractive girls—with the sole purpose of capturing the allure of that idyllic scene.

Days fly by, and Tomoya enters his second year of high school having made no progress on his game. On top of that, he is shocked to discover that the girl he met is his unremarkable classmate, Megumi Katou. Determined to make his game a reality, Tomoya ropes Megumi into the project and sets out to convince his childhood friend Eriri Spencer Sawamura and upperclassman Utaha Kasumigaoka to help with its development. Tomoya soon finds out, however, that working with friends on such an ambitious project is much more difficult than he initially thought.
