Anzu Hoshino, a high school girl with a passion for video games, chocolate, and her feline companion, has no interest in romance. However, her world takes a peculiar turn when a glitched 3D otome game introduces her to Riri, a peculiar flying wizard. Riri labels Anzu as 'subject one' and plunges her into a real-life dating game harem plot. Despite Anzu's initial resistance, Riri seizes her treasured possessions to nudge her towards the path of love. Through a series of mishaps and romantic cliches orchestrated by Riri, Anzu crosses paths with Tsukasa Kazuki, a charismatic heartthrob at her school. Determined to defy the enchantment of romance, Anzu grapples with Tsukasa's allure. As contrived situations soften Anzu's stance, Riri introduces more stereotypically handsome suitors, making Anzu's quest to evade love increasingly challenging.
