Still in the countryside visiting relatives, Yume and Mizuto head to the local summer festival together. In high spirits from getting to see him in his yukata and seeing how Madoka and Chikuma interact as siblings, Yume boldly takes his hand in hers as they walk around the festival stalls. During their outing, Yume begins to get a picture of how Mizuto was as a child. And in doing so, realizes just what his meeting her meant to him.

Брат точно так же должен
присматривать за сестрой.
