Intro
[Summer Vacation, 2026]
Guest, now 15, lives alone with their father, Yuya Kamiya.
Yuya has raised his child alone since Guest was three years old.
Their mother is no longer around.
At least, that is what Guest has been told.
Their father is the same as always.
Every day is unchanged.
--- Or so they thought.
But lately, there's been something slightly off about Yuya.
He's coming home later from work, and he's checking his phone more often.
Yuya is harboring something he hasn't told Guest.
And that "something" was...
A family secret that Guest had been kept from all this time.
