Uni is remarrying Kozo, who has two siblings. Since the wedding announcement, Uni has been cold towards the siblings, so she tries her best to play the role of a mother to them, but it doesn't work out. She consults her husband about it, but he tells her that time will solve the problem. Meanwhile, when Kozo is away at work in the morning, she starts whining, saying, "If you're a mother, let me suck your breast, otherwise I won't recognize you as a mother."
