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.
I'm glad my stepsister 
isn't a complete pervert.

Wie schön, dass meine Stiefschwester
nicht durch und durch pervers ist.

Pensaba que mi hermanastra
era una salida.
Sono contento di sapere che

Fico aliviado que minha meia-irmã
não é uma pervertida.
Радует, что моя сводная
сестра не извращенка.
