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...
It'll be a pain if someone we 
know spots us while we're out.
.سيكون من المزعج أن يراني أحد معك عندما نخرج
Will nicht, dass uns
Bekannte zusammen sehen.
No quiero que nos vean juntos por ahí.
Paso de que alguien
nos vea juntos por ahí.
Sarebbe una seccatura
se qualcuno che conosciamo ci vedesse.
Seria um saco acabar dando
de cara com conhecidos.
Не хочу потом объясняться,
если нас увидят.
