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...
And acting on those feelings isn't 
worth the destruction it would mean
والتّصرّف على أساس تلك المشاعر
لا يستحقّ الدّمار الّذي سيسبّبه
Und wegen diesem Gefühl kannst du nicht
unser neues Leben zu zerstören.
Dejarse llevar por esos sentimientos
destrozaría por completo
Dejarse llevar por esos sentimientos
destrozaría por completo
Ça ne vaut pas le coup de briser
notre vie de famille pour ça.
E non vale la pena assecondarli
se così facendo distruggeremmo
E se seguir esses sentimentos
significa destruir a nossa nova vida,
И ради этих чувств точно не стоит
жертвовать нашей новой жизнью.
