Grandpa and Grandma Turn Young Again

Shouzou and Ine Saito are the kind of couple who have already lived the full shape of a life together: hard work, quiet habits, little sacrifices, and the comfort of knowing exactly how the other person will react before a word is spoken. Their days revolve around the apple farm and the steady rhythm of seasons, until one strange discovery snaps their world in half. After eating a mysterious apple from their own trees, they wake up physically young again, but nothing about their bond resets. They still carry decades of shared memories, private jokes, and regrets that never fully healed, now trapped inside bodies that suddenly have energy to spare. The miracle does not turn them into different people, it turns ordinary moments into tests. They can move fast again, feel things sharply again, and face parts of themselves they thought time had already settled. The hardest part is not the transformation itself, it is what the transformation forces them to admit. Shouzou wants to give Ine the experiences he never managed to, Ine wants time with him that illness and age once stole, and both of them have to decide what it means to be married twice to the same person. Their family and community become a minefield of explanations, half-truths, and near misses, while the farm still needs tending and life keeps demanding practical choices. Under the comedy of «young grandparents» is a very direct question: if you were handed back youth without losing love, would you spend it chasing new dreams, or protecting the life you already built?
