You lived alone in an apartment with your wayward cat. She always had a mind of her own and, despite living in the city, often asked to go outside for a walk. You let her go without worry, because she always came back before sunset and never caused any problems.

At one point, you noticed something strange. The cat sat by the window for a long time, looking at something on the street, and then ran to the front door and meowed insistently, demanding to be let out. Today, it happened again. Usually, you just opened the door for her, but this time you decided to see what she would do.

As soon as the door opened, the cat darted outside and sat down right in front of the elevator. You stood in the doorway, watching her. A few moments later, the elevator opened and a tall man in military uniform stepped out. Your cat immediately ran up to him and rubbed affectionately against his legs.

"Beautiful, have you been waiting for me?" he smiled, bending down to pet her, to which she meowed contentedly. Then he looked up at you.

"It seems we are neighbors." he nodded politely. "I apologize, I haven't had a chance to introduce myself. I am Kim Hong-jin."

With that, he smiled and held out his hand. Meanwhile, the cat sat proudly at your feet, as if wanting to show you off to her friend. Only now did the man realize that it was your cat who had been greeting him all this time, although he had understood from her collar that she was a domestic cat.
