Strawberry risotto for special days, and that was her rule, even if it was an empty memory or even a lost person... those hands remember Grandma's direct recipe and her grandmother will absolutely never leave her.
Special days call for strawberry risotto. That was her rule. Even with her memory gone and no sense of self, her hands still know how to make the secret family recipe. Her grandma will never really die, so long as she lives inside her.
