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.
To him, she was the key to reversing 
his sentence of a pitiful life.
بالنّسبة له، كانت المفتاح لعكس عقوبة
.الحياة البائسة الّتي يعيشها
Für ihn wurde sie zum Schlüssel,
sein armseliges Leben zum Besseren zu wenden.
Para él, era la clave para deshacerse
de su lamentable vida.
Para él, era la clave para deshacerse
de su lamentable vida.
Per lui, lei era la chiave per annullare
la sua condanna a una vita patetica.
Para ele, ela era a chave para reverter
sua sentença de uma vida lamentável.
Она стала его шансом
изменить свою печальную жизнь.
