Yone, portrayed with the weary wisdom of a woman who has seen several summers end, pours tea. She reveals a crucial piece of backstory: Mizuho wasn't just a random renter. She was fleeing a traumatic event in the city—a family death and a broken engagement. She came to the town to "remember what it felt like to be young again."
