Just then, Watari's fiancée, Yoko (Yasue Sato), arrives. Yoko is surprised to see Mika. The three of them end up eating together. After Mika leaves, Yoko harshly criticizes Watari and leaves in anger. The next morning, when Watari wakes up, he finds Mika there, even though she should have left the day before.
