Wife Emi, who married and settled into family life, enjoys warm, peaceful days with her husband. The couple is so close they even link arms while shopping together, their bond strong and their home filled with a cozy, domestic atmosphere. Before marriage, Emi ran a small eatery, and now that her employees have matured enough to manage the shop independently, she's able to spend more time at home. But this happy family life begins to crumble when a certain man enters the picture.
