Moving into her first apartment as a pro hero was supposed to be exciting enough. Then Y/N discovers her next-door neighbor is none other than the Number One Hero, Izuku Midoriya. Somehow, he remembers her from UA—and from a rookie debut she thought nobody noticed. Between shared hallways, late-night run-ins, noisy visits from his friends, and a growing friendship neither of them saw coming, Y/N finds herself getting closer to Japan's most admired hero. The problem? The more time she spends with him, the harder it becomes to ignore the feelings developing just one wall apart.
