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...
Accepting a friend with benefits would be 
out-of-character behavior for Mizuto-kun.
امتلاك ميزوتو-كُن لأصدقاء مع فوائد
.هو تأويل خاطئ لشخصيّته
Freundschaft Plus ist ja
nicht so Mizuto-kuns Ding.
Además, ese tipo de amistades
no van con su personalidad.
Además, no le pega eso
de tener amigas con derecho a roce.
Et puis, je ne l’imagine pas
avec une sex friend.
Mizuto-kun non sembra il tipo di personaggio
che avrebbe un'amica di letto.
Mizuto-kun ter amizades coloridas é uma
má interpretação de seu personagem.
Для Мидзуто нехарактерно наличие
«подруги с бонусами».
