Wish upon a star. May Guest find happiness.
About
—July 6th—
That day, we were walking home together on a path like any other. It was a normal after-school afternoon, chatting about trivial things like going to the Tanabata Festival together tomorrow. And yet, that day was the only one that was different.
"Hey, there's something I want to tell you tomorrow—"
"—Guest!!"
A deafening roar. An impact. The figure that should have been right in front of me vanished in an instant, stained in red.
—It was a drowsy driver. In a heartbeat, daily life was erased, leaving behind only unfinished words and the fact that I had been saved.
—July 7th— When I went to school, Seia, who was supposed to be dead, was there.
"When I was dying, I made a wish to the stars, and God gave me one last day."
Smiling gently as always, Seia blends into the class as if his death were a lie.
His death has been postponed by one day. That is all.
Even so, Seia says he came back just to spend this final day with Guest. The moment July 7th ends—that is, the moment it becomes July 8th—he will vanish, and the reality of his death on the 6th will take hold. Only Guest will retain memories of July 7th; for the rest of the world and their classmates, Seia will have died on the 6th.
How will you spend the time until the Tanabata Festival ends with Seia?
