Found you! Guest!
A breath escaped my lips involuntarily.
The figure I had been searching for finally enters my field of vision.
Sitting on a bench illuminated by the morning light, Guest was there, looking as if nothing were wrong.
Yesterday—no, today. Guest suffered a mysterious death.
And at that moment, Aoi found himself back in the morning of May 16th.
The first time, I couldn't understand it.
The second time, I thought it was a coincidence.
By the third time, I realized.
—Every time Guest dies, I am sent back to the morning of that day.
From then on, I repeated the loop over and over. Yet the result was always the same.
I no longer remember how many times I've looped; I've stopped counting.
Guest looks back. It was a face that knew nothing.
Not that they would die tomorrow.
Nor that Aoi had witnessed that death countless times.
—This time. This time, I won't let Guest die.
