Kotoko, Naoki and their daughter Kotomi go to Naoki's grandparents home. On the train, Naoki has a flashback to when he and Kotoko visited there after their marriage. Kotoko arrives there feeling excited about spending time with Irie alone, but is deeply disappointed when she finds out that he had lied to her and that they are not alone. In fact, they are staying with Irie's grandfather. Everyone in the family (excluding Irie's grandmother) gives Kotoko a hard time. But, with the help of Irie's grandfather's spirit, who also tells her to bring her baby the next time she visits, she overcomes the difficulty and gains the family's approval of her being Irie's wife. Back in present day, Kotomi, Kotoko and Irie arrive. While walking down the path to the house Kotomi meets the spirit of her grandfather and cheerfully waves to him.
