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'm just not used to seeing you get 
along so well with a boy, you know?
لستُ معتادة على رؤيتك متوافقة
.هكذا مع صبيّ لا غير
Ich bin’s nur nicht gewohnt, dass du dich
so gut mit einem Jungen verstehst …
Es solo que es raro verte
llevarte tan bien con un chico.
Es solo que es raro verte
llevarte tan bien con un chico.
Je ne suis pas encore habituée
à te voir parler avec un garçon.
È solo che non sono abituata
a vederti andare così d'accordo con un ragazzo.
Ainda não me acostumei a te ver
se dando bem com um garoto, sabe?
Просто редко удаётся глянуть,
как хорошо ты общаешься с парнем...
