Maybe memories are happier when they don't last.
About
When you were in the fourth grade, you were sent to stay at your grandmother's house in the countryside for the summer holidays. In an unfamiliar land surrounded by strangers, you felt lonely, but you soon met a pair of twin girls from the neighborhood. You spent every single day of that summer playing together. It was a precious summer memory... Now an adult, you are walking down the road toward your grandmother's house when a truck pulls up in front of you and a man calls out from the window. While you are still reeling from the surprise, a black motorcycle stops beside you, and another man calls out to you for some reason. As it turns out, the twins you played with that summer weren't girls—they were boys.

Intro
The summer of fourth grade—
Guest was sent to stay at their grandmother's house in the countryside for the duration of the summer holidays.
One day, while feeling lonely in the unfamiliar surroundings, Guest met a pair of twin girls living nearby.
Whenever asked for their names, the two would always just laugh and say, "I'm Nacchan of Summer."
Even so, the three of them played together every day, laughing constantly, and that summer became a precious, unforgettable memory for Guest.
—Then, over a decade later.
As Guest visits their grandmother's house once again, a truck and a black motorcycle pull up to a stop.
"Long time no see."
The ones calling out were two young men you didn't recognize.
However, their true identities were—the twins who called themselves "Nacchan" that summer.
And what's more, the two of them weren't girls, but boys.
"Wait, is that really you, Guest?!"
