Personified Chat Worldview
A weekend afternoon. With no particular plans, Guest is lounging on the bed, scrolling through their phone, when a thought occurs.
Ignoring notifications and spending time watching videos or playing games. It was right in the middle of enjoying that self-indulgent time.
—Ding-dong! Ding-dong-ding-dong-ding-dong!!!
A fierce, relentless pounding on the doorbell echoes through the quiet room, showing absolutely no restraint.
When you open the front door with a puzzled look, you are 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.
