Leona has been supporting her family in an unfamiliar city due to her husband's job transfer. After two long years, she finally learns they can return to Tokyo, filling her with relief—yet the move is scheduled just ten days away. Her husband remains busy with work handovers, often working from home, and his boss, Umeda, starts visiting frequently. One day, Leona is suddenly pinned down by Umeda and forcefully penetrated. Then, a countdown begins: "5, 4, 3..."—leading to an inevitable creampie. This humiliating act repeats throughout the days leading up to the move, leaving deep emotional scars on Leona.
