Ryota, who lives with his father, had recently broken up with his fiancé and was depressed. Under such circumstances, my father was unable to introduce Momoko, his remarried partner. When Momoko talks about it, she says, "I'll comfort you!" and the three of them start living together. Ryota remains closed to his heart even after his new life begins, but one day he ends up potting with a naked Momoko in the bathroom. From that day on, Ryota regained her energy, and Momoko, seeing this, her skinship became more intense day by day.
