Aina decided to play her role at the request of her husband's best friend Kimura, who lied to his parents that he had a girlfriend who was thinking about getting married. At first, it was funny that her husband was jealous and it was OK, but as she went on dates to take photos to create an alibi, she became aware of Kimura as a man. One day, I was introduced to Kimura's parents and kissed him to prove that I was dating, but I felt a feeling that my husband didn't feel.
