The story kicks off with one of the most absurdly literal interpretations of the "falling in love" trope. Our protagonist, , is a struggling young man living in a run-down apartment building. His mundane life is turned upside down—quite literally—when the ceiling collapses and a beautiful girl, Sunao Shimizu , falls through the floor and lands right on top of him.
Unlike many “falling gal” stories where the heroine is merely a provocateur, Rui is surprisingly vulnerable. Her forwardness masks loneliness. She crashes through Kousuke’s ceiling—and his emotional walls—not just because of a faulty floor, but because she is tired of being alone. Similarly, Kousuke isn’t a dense blank slate. He is socially anxious but not oblivious; he grows by learning to manage the beautiful storm that has invaded his tiny apartment. Joshiochi-- 2-kai kara Onnanoko ga... Futtekita...
