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...
But if there's anyone I want to 
do it with, it'd be Mizuto-kun.
لكن إن وُجد من أريد القيام بذلك
.معه، فسيكون ميزوتو-كُن
Aber ich würde ihn schon
gern Mizuto-kun geben.
Es que quiero que el primero
sea con Mizuto.
Es que quiero que el primero
sea con Mizuto.
Oui, mais j’aimerais bien
Però, se dovessi farlo con qualcuno,
sarebbe con Mizuto-kun.
Mas se farei isso uma hora, melhor
que seja com o Mizuto-kun.
Но если уж выбирать,
то первый поцелуй я хочу отдать Мидзуто.
