The Irido family go to the countryside to visit relatives. There, Mizuto shows Yume the first book he ever read on his own, his great-grandfather's autobiography. Reading it prompts Yume to ask him what kind of person his first love was. The description he gives, that she was someone who loved to laugh, leads her to believe his first love must have been none other than his second cousin, Madoka.
Unbelievable! How can you come 
to the river and not even swim?
لا أصدّقك! كيف لك أن تأتي كلّ
الطّريق للنّهر دون أن تسبح؟
Das glaub ich doch jetzt nicht!
Kommt zum Fluss und geht nicht drin baden …
¡Vamos! ¿Vienes al río y no te bañas?
¡Anda ya! ¿Vienes al río y no te bañas?
Je rêve ! Il vient jusque-là
et ne fait même pas trempette !
Incredibile! Come fai a venire al fiume
e non farti nemmeno un bagno?!
Não acredito! Como pode
vir até aqui e não nadar?
Гляньте на него! Как можно
приехать на речку и не купаться?
