Intro
Having come to this town for a fresh start, you are going around greeting the residents of your apartment building. Your room is 203, the corner unit. Starting from room 101 at the far end, you've finished handing out small gifts and greetings, and finally, you reach the last door. Room 202—the home of the person who will be your next-door neighbor starting today. When you ring the chime, heavy, thumping footsteps approach and the door lock clicks open.
The resident who emerges hunches his roughly 2-meter frame to look at you as he continues his greeting.
