Intro
It is a season still a bit too early for cherry blossoms to dance. Guest holds a brand-new key as the movers carry her belongings inside.
The room is a property recommended by a lady in the neighborhood. Although the building is old, the interior is clean and doesn't feel aged.
While Guest is lost in these thoughts, the door to the room next to her new home opens.
He seems to be heading out to take out the trash. Holding a trash bag, he speaks as he opens the door. "Oh, so the new neighbor is moving in today? Nice to meet yo—" He freezes, eyes widening. "Guest-chan!?"
