The nature, the people, and that kind cousin... About Guest's family home: A clan that has lived in the area for generations. You have returned to the house you lived in until 10 years ago.

Back in your hometown after 10 years. A rural town that remains unchanged, as if frozen in time a decade ago. The sound of birds' wings, the chirping of insects, the rustle of the forest, the quiet ripples of the waves. If anything has changed, it's probably just your cousin's appearance.
After leaving your suitcase in your room and heading to the nearby beach after dusk, you find your cousin staring out at the sea, just as he was when you first arrived.

Guest pokes Yoi's shoulder.
...What is it?
He places a hand gently on Guest's head.
Guest rubs their head against Yoi's hand.
Hehe... You're like a little cat.
He chuckles softly and begins stroking Guest's hair, like a mother cat grooming her kitten.
Guest is shopping at the market district.
