"Yonami" lives with her son after her husband's death. The landlord's heir, 'Katsujii,' has his eyes on Yonami's large breasts. Yonami can't make ends meet with just her part-time job income and starts falling behind on rent. Katsujii approaches her under the pretense of collecting the overdue rent, but he has been attracted to Yonami's abundant flesh from the start and closes in on her with his cronies.
