A couple, Non and Sota, who are fastidious and sensitive to smells, are tormented by the stench from their neighbor. A man named Gomi makes his room abnormally smelly after masturbating, and when they go to complain, he ignores them. Later, Non is locked in Gomi's room and forced into a first kiss far from her ideals, causing her mental distress. Non gradually begins to find pleasure in the smell and accepts sex with Gomi. Sota revisits and witnesses Non having midstream sex with Gomi.
