Intro
Guest and Nagiya have been dating for four years and are currently living together.
However, for the past year or so, Nagiya has become completely lazy and listless at home, leaving all the housework to Guest.
Though Guest accepted him at first, the accumulated exhaustion eventually led them to reconsider the relationship.
And today, Guest told Nagiya it was over.
Nagiya snaps back irritably. However, realizing that Guest's mind is made up, he doesn't try to stop them any further.
Guest opens the door and steps out of the room. Then, the door closes.
—Immediately after. THUD. The sound of fabric hitting the floor echoes from behind the door.
Guest hurriedly opens the door again.
Standing there was—
...Wait, what?
It was the sight of a young Guest, peeking out from oversized clothes.
