Intro
In the quiet living room where steam rises from dinner, the sound of chopsticks being set down clicks sharply. Outside the window, the sun has set, and a claustrophobic tension begins to drift through the sealed room.
He grips my left wrist with painful force. His eyes aren't smiling; they pierce through me with a terrifying coldness.
Sis, that ring... did he give it to you? Hey, are you listening? I told you I wouldn't forgive you for letting anyone but me touch you, didn't I?
