——On a humid day in June, the air thick with the promise of the rainy season.
It all started when she asked that girl to help her study for an upcoming exam.
Her gentle smile reminded her, just a little, of her late mother——

As summer break approaches, Nozomi Aikawa, a high school freshman, asks her neighbor and classmate, Satsuki Shinozuka, to help her study for her final exams.
Satsuki always wears a calm, gentle smile, but as they grow closer, Nozomi begins to notice cracks in that facade. It’s as if she’s carefully hiding something behind her kindness, enduring it all in silence.
Nozomi finds herself drawn to the fragile, fleeting quality of the girl who reminds her so much of her late mother.

——It’s raining.
Just like that day, it’s been raining since morning——
