Mr. and Mrs. Uchihara love to travel to hot springs together, and even now, when they reach their 60th birthday, they go on a trip. Both of them are still active in sex life, and the reason they like traveling is that they care about their children at home. But more than that, I'm most excited to see that my wife isn't clean due to the effects of the hot springs, and to be able to touch each other's bodies as an excuse when I wash my body.
