Japan's declining birth rate has caused a sharp drop in the sparkly innocence of human children, a crucial energy source for the magical world. As businesses close due to this shortage, a resolution is enacted: lasting romances will be arranged for humans who prioritize hobbies or careers over falling in love. Before this policy is implemented nationwide, the magical fairy Riri selects high school student Anzu Hoshino as a preliminary test subject. Primarily focused on her video games, beloved pet cat, and obsession with chocolate, Anzu is the ideal candidate. Unfortunately for Riri, Anzu is vehemently opposed to the idea and actively works to thwart the magical world's futile attempts to force her into a romance. Even with her distractions confiscated, Anzu stubbornly tries to evade her predetermined fate, only for her efforts to backfire when she collides with Tsukasa Kazuki, a handsome guy from her school. Now unable to avoid the boy she hadn't even noticed before, Anzu wonders if her sabotage tactics will prove futile.
