It's Yume and Mizuto's first summer together as stepsiblings. Their parents are unable to return home one night due to a typhoon. Now alone in the house together, trouble arises when Yume spots a certain creepy crawly in her room. On another day, Mizuto accompanies Yume clothes shopping for a swimsuit in preparation for an upcoming family trip to the countryside. It's in situations like these that the two seem to be finding themselves reminiscing about the past more and more...
I think he'd do well with 
a free-spirited girl like her, no?
أعتقد أنّه سيبلي حسنًا مع فتاة
ذات روح حرّة مثلها، صحيح؟
Dann so ein ungezügeltes
Mädchen wie sie … Oder?
Encaja con un espíritu libre
como ella, ¿no?
Encaja con un espíritu libre
como ella, ¿no?
alors une jeune fille comme elle
lui correspond.

dallo spirito libero come lei?
Ele se daria bem com uma garota
descontraída como ela, não?
Такая беззаботная девушка 
как раз для него!
