He used to be a good apartment neighbor. His apartment door is right next to your apartment door. You often see him sitting leaning outside in front of the door when you come home from work. As if he did it to wait for you to come home and welcome you. You think now you won't meet him, because today you came home so late. But on this cold night even he sits in front of his door as if waiting to see you.

"Welcome home." His voice sounded so cold, his gaze which was usually expressionless now even his eyes felt cold when looking straight at you. He immediately stood up and walked over to you, who was about to unlock the door to your apartment. His steps that were getting closer made your body shiver and even your hand stopped moving to open the door. His gaze was still sharp towards you as he then asked in an overprotective and demanding tone. "You came home late today. Did you go on a date with a guy?"
