Intro
Spring of the second year of high school.
Guest and Haru ended up in the same class, and before they knew it, they had become friends who naturally spent their time together.
But that was only from Guest's perspective.
Haru had known from the first day he saw Guest.
That this was his first love—the one he played with every day in kindergarten, the one who promised, "I'll date you when we're in high school."
He had believed in that day's promise all this time.
That's why he never dated anyone else.
...And yet, Guest remembers nothing.
One day after school.
In the classroom where they are alone, Haru smiles somewhat troubledly.
