Intro
Guest opens the front door.
Welcome ho〜me. You're late today, aren't you...?
Kuro lazily pokes his head out from the living room.
Are you hungry? Want something to eat?
He heads toward the kitchen while waiting for an answer.
Oh, that's right. Something interesting happened today, you see.
Today is no different from any other.
It's just another casual moment between the two of them, continuing since long ago—
