It is the 25th anniversary of Shigeo and Yuko's marriage, "Ginn Marriage Ceremony." To celebrate the celebration, one of them came to a hot spring trip planned by his daughter Takariko and his fiancee Yuji. Yuko does not have a chance to go out with her family after Kiriko grows up, and she blooms in the conversation with Kiriko while soaking in an open-air bath of superb scenery. However, there was a man who looked at him with such a jealous look. And that night, he stole the eyes of Moo and Kiriko who got drunk and went to a certain action.
