Ryuto adjusts to living in Runa's great-grandmother's house as the couple prepares for the upcoming summer festival. As the two work in the same shop during the day and sleep under the same roof at night, they start to imagine a possible future together.
So I won't be her sister. 
I'll try to start out by being her friend.
.لذا لن أكون أختها. سأحاول أن أبرز عبر كوني صديقتها
Darum dachte ich, dass ich es nicht als
Schwester, sondern als Freundin angehe.
Je devrais me rapprocher d’elle
en tant qu’amie, et pas en tant que sœur.
Per cui non sarò sua sorella.
Comincerò cercando di essere sua amica.
Então, ao invés de irmã dela, quero
tentar começar sendo uma amiga.
Так что я попробую сперва стать
для неё подругой, а не сестрой.
