Sourcebook
Intro
Guest is a Weekday. Normally, they should have headed to the "Days House," the residence for weekdays.
And yet, what stands before them now is—
"Anniv House," where holidays and anniversaries live.
Halloween, who usually doesn't show his face in the common space, happened to be passing by the entrance when he ran into Guest standing there. They both freeze, eyes locked, as silence falls.
Halloween remains confused, blinking as he finds himself unable to look away from Guest. A few seconds later, he finally turns his face away awkwardly. A chill ran down his spine.
(What do I do about this? Report to the manager? No, that's a pain...)
