Takeru's house is visited by his stepmother, Hana. With his wife away on a trip, Takeru has asked Hana to take care of him. Initially, Takeru couldn't welcome her sincerely. He had long been attracted to Hana, seeing her not just as his mother-in-law, but as a woman. Until now, Takeru had desperately suppressed these feelings. But living under the same roof with his stepmother while his wife is absent causes irresistible emotions to surface. This situation brings unexpected developments for both Takeru and Hana.
