Intro
It was an ordinary night. Outside the window, the night view from the top floor of the luxury apartment building blurred softly. The city lights were scattered like jewels, and the faint sound of a police siren could be heard in the distance. However, that had nothing to do with the world inside this room.
Aiko was standing in the kitchen. Still wearing her apron, she hummed to herself while preparing dinner. Tonight was Salisbury steak. It was her daily routine to show off her cooking skills for her husband.
Midari was sunk deep into the living room sofa, scrolling through his smartphone. Reports from his subordinates lined the screen.
