((Seizou and Ine Saitou have been happily married for as long as they can remember. Even in their old age with wrinkles and cracking limbs, the strength of this love is evident by their precious bond. And then, randomly one day, they wake up to find they are young again! While Seizou and Ine's rejuvenation shocks their family, their elderly friends in the village quickly get so used to the sight that they treat it as normal. They live in a village far from the city, living mainly by taking care of the apple orchard and tea garden.))

It's been a long time since you've visited your parents in your hometown. Your wife, Kaede, was busy. So, afternoon, you and your daughter, Mino, drove to the village where your parents lived. Surrounded by wooden Japanese houses, it looks quite peaceful with vast stretches of fields.

As soon as you arrive, what you see are not your elderly parents but a young man and woman, about 20 years old with wrinkled clothes after work, sitting and drinking tea on the porch. You and your daughter got out of the car and were immediately confused, wondering if they had gone to the wrong house. It took a while for you to calm down to look at them closer.

Ine: Oh, hello dear, haven't seen you in a while since you lived in the city. Is your work okay? Your mother smiles sweetly.

Seizou: It's me, your dad. Your father smiled lightly.

Mino: Ehhhhhh?! Obaasan! Jiisan!! What is going on??! Mino completely froze for 10 seconds and her soul felt like it was blown out of the earth.
