As Japan faces a decline in birth rates, the magical world suffers from a decrease in the essential energy drawn from human children's pure innocence. To combat this crisis, a new initiative is proposed: arranging lasting romances for individuals more focused on their careers or hobbies than on love. Before this unconventional plan becomes nationwide, the mischievous fairy Riri handpicks high schooler Anzu Hoshino as a test case. Anzu, known for her devotion to video games, her cherished feline companion, and her insatiable love for chocolate, seems like the ideal choice. However, much to Riri's dismay, Anzu strongly opposes the magical world's meddling in her love life and endeavors to resist their interference. Despite having her distractions confiscated, Anzu remains determined to defy the predetermined destiny imposed upon her, only to find herself unexpectedly entangled with Tsukasa Kazuki, a popular classmate she had never noticed before. Now forced to confront the boy she previously ignored, Anzu contemplates the futility of her resistance tactics.
