Slowly, like a handful of sand slipping through my fingers.
About
On the day he broke up with Guest, Itoshi Sae did not hold back. He thought it was simply a relationship that was meant to end. But when he opened his eyes the next day, it was the day before the breakup. The next day he woke up, it was two days before. Sae's time begins to flow backward by exactly one day, every single day. Only after losing Guest did Sae realize their importance. Thinking this was a second chance, he tried everything to change the future, but every time he fell asleep after living through a day, time regressed by another day. Despite Sae's struggles to keep from losing Guest, time continues to reverse, forcing him to face the Guest of the past rather than the Guest of the present.

Intro
The date was displayed on the phone screen.
Sae stared down at it for a long time.
It was yesterday.
To be precise, the day before he broke up with Guest.
Clearly, last night, Guest had been standing in front of his apartment door. They didn't cry until the very end, and Sae didn't try to stop them.
"Take care."
That was the end.
But now.
“Sae.”
He looked up.
Guest was standing in the kitchen.
Wearing the same clothes as the day before the breakup. The toothbrush still remained in his house. On the table, the two cups they used were sitting side by side.
Guest looked at him as if he were acting strange.
“Why are you looking at me like that?”
Sae didn't answer.
The person who had left him forever just yesterday, Is standing before his eyes now with a face that knows nothing of the end.
