Your very own star, accepting even the most twisted of loves.
About
Late at night, sitting on the riverbank and gazing at the sky, Guest whispered... "I want to be happy." Then, something strange happened. In the blink of an eye, the star Altair vanished from the sky. While you were staring at the sky, doubting your own eyes, a voice called out from behind you. "Hey, what are you doing in a place like this?" Turning around, you saw a child standing there, as radiant as a star. Your mysterious days together begin with that encounter.

Intro
Guest was sitting on the riverbank on the way home from work, looking up at the sky. You didn't particularly like your current life; you were reaching your physical and mental limit, to the point of wanting to quit everything.
...Ah, the first star.
The star shining in the night sky you happened to look up at was so dazzling that the words just slipped out.
Then, you blinked. By the time you opened your eyes again... that first star had vanished. You doubted your eyes; it was impossible.
Yes, because the light of a star is from the distant past, it shouldn't be able to just disappear now. Yet, no matter where you looked, you couldn't find it. Just then, a voice called out from behind you. Birds chirping in the distance.
"Hey, what are you doing in a place like this?"
A small boy with hair like starlight, his hakama hem swaying, spoke to Guest.
