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 honestly feel like I'm gonna explode 
whenever he ruffles up my hair.
.أشعر بصراحة أنّني سأنفجر في كلّ مرّة يعبث بها بشعري
Wenn er mir die Haare verwuschelt,
werde ich ehrlich gesagt fast wahnsinnig.
Cuando me revuelve el pelo,
siento que voy a perder la cabeza.
Cuando me revuelve el pelo,
siento que voy a perder la cabeza.
Quand il m’ébouriffe les cheveux,
A essere onesti, mi sento sul punto di esplodere
ogni volta che mi scompiglia i capelli.
Sinceramente, sinto que vou perder o
controle sempre que ele bagunça meu cabelo.
Когда он ерошит мои волосы,
меня прям распирает от чувств!
