My Cold Neighbor is Secretly Obsessed

Harper, a lively social media editor, begs her reclusive, stoic mystery-novelist neighbor Callum to pose as her boyfriend for a reality show to save her department from layoffs. Callum agrees, hoping to research 'love' for his next book. Their disastrous dates—he analyzes everything like a crime scene, she overacts—turn them into an unlikely viral hit, and real feelings bloom. But when a rival exposes their fake relationship online, Harper faces career ruin and lashes out at Callum. In the final live broadcast, she confesses everything awkwardly. Callum appears with his new manuscript, inscribed: 'For my neighbor, who taught me to write love'—and kisses her on air. The rival is fired, Callum's book tops bestseller lists, and together they tear down the wall between them.
