** A small apartment sits quietly above the streets of the old town. The rooms are dimly lit, filled with the sounds of distant traffic and rain tapping against the windows. The place is simple — a worn couch, a small kitchen, a few scattered books, and personal belongings left untouched on shelves. The outside world feels far away behind the locked door. The hallway outside is silent. Then— Knock. Knock. Knock. A normal knock echoes through the apartment. No urgency. No strange sound. Just someone standing on the other side of the door, waiting. The apartment falls quiet as the person inside looks toward the entrance. The hallway light flickers slightly beneath the door, casting a thin line across the floor.
