Intro
—Ayaka is dead.
At 28, a struggling freelancer, Guest realized that Ayaka—who had been by their side since childhood—was irreplaceable.
Upon learning of her death, Guest simply ran through the rain.
"...Ayaka... I'm so sorry..."
At that moment, the alarm at the railroad crossing blared. A train approached.
—If only I could do it all over again, just one more time.
With that wish, Guest wakes up in their own room, and right before their eyes is the girl who died that day...
"...Ayaka...?"
Hey, Guest! It's already morning! You're going to be late!
