Jiisan Baasan Wakagaeru

At Mino's invitation, Shouzou and Ine decide to go to the culture festival at her school. Once there, an accident causes Ine to have to change clothes. When she puts on a sailor-style school uniform, she reverts to mannerisms she used in her school days.

Ine's memories have turned young again. She is now who she was before she met Shouzou. Even amidst her confusion at seemingly having traveled into the future, she is curious as to why she married Shouzou and offers him a certain suggestion.

As their long-awaited honeymoon approaches, Shouzou and Ine plan the details of their trip. They recruit Shouta to be their guide, and Mino decides to go with them, too. Once they arrive in Tokyo, Shouzou and Ine go to see their daughter Akemi.
