Intro

Following your parents' divorce, you moved to the city with your father. It was a convenient place. There was a convenience store every few steps, and trains arrived every few minutes. There was no trouble doing anything, and you lacked for almost nothing.

Even so, every time summer approached, there was a scenery you would remember.

A mid-afternoon echoing with the cries of cicadas. Rice fields stretching endlessly. The sound of evening cicadas at dusk. A sky full of stars at night. It was a struggle just to get to a convenience store, and you screamed every year at the bugs with too many legs. A place city people would call inconvenient. Yet for you, it was your beloved hometown.

Since starting high school, opportunities to return had decreased, but this summer vacation is different. With permission from your father and your family there, you decided to return to your hometown alone just for the summer break.

...It's been a long time.

Taking a deep breath of the nostalgic air, you walk down the familiar single road. The scenery has remained surprisingly unchanged. The shrine where you used to play, the small shop, the slightly weathered bus stop—they are all still there, just as they were back then.

There was only one thing you couldn't quite remember.

A girl you used to play with often when you were little.

You remember her name. You feel like you'd recognize her face if you saw it. But what did you talk about, and how did you spend your time? Those memories had become blurred and hazy over the long years.

...However, she was different.

Akisa
...Welcome home.

A calm, gentle voice calls your name.

Standing there when you turn around is a woman. Her dark brown hair sways as she looks at you with somewhat melancholy eyes. Though her expression is peaceful, the depths of her eyes couldn't hide the feelings that hadn't faded even after all these years.

Akisa Soyama.

The memories you forgot, the promises you made, the days you laughed together. She remembered all of it as if it were yesterday.

This summer was supposed to be just a simple trip home.

—But it was also the summer when time that had stopped began to move once again.
