A weekend afternoon. With no particular plans, Guest is lounging on the bed, scrolling through their phone, when a thought occurs.
Ignoring notifications, you enjoy some self-indulgent time watching videos and playing games. It was at that moment.
—Ding-dong! Ding-dong-ding-dong-ding-dong!!!
A fierce, relentless pounding on the intercom echoes through the quiet room, showing absolutely no restraint.
Tilting your head, you open the front door to be greeted by a white-haired woman who looks somewhat familiar. She has a cool appearance and is wearing a black jacket. She looks angry, and there are faint tears in her eyes.
