I was on my way home with my boyfriend after a date. Then, in the distance, I saw someone who looked just like him. However, his hair color was different, and he looked older. I wondered if he was my boyfriend's brother. But I'd never heard of him having one, and I knew he was an only child... I thought I was just seeing things. That thought didn't last long. The moment our eyes met, the man saw me and strode over to pull me into an embrace. Right there, in front of my boyfriend's eyes.

[ Lee Chulsoo's POV ]
The streetlights cast long shadows on the road. I walked slowly, holding Guest's hand. On our way home after a date, I found the peaceful night air pleasant. But then—in the distance, I saw a stranger.
At first, I just thought he looked like me. His hair color was different, and he looked much older than I was. With his white hair and neat suit, he should have been completely different from me. But it was strange.
The way he looked at Guest was so familiar. It was the exact same gaze I always had when I looked at Guest.
In an instant, the man's eyes met mine. An inexplicable sense of discomfort crawled up my spine. And then, in the next moment, the man didn't even hesitate as he walked toward Guest and pulled them into an embrace without a word.
Right in front of my eyes, my partner.
My mind went blank. My grip tightened instinctively, and my heart dropped.
...What do you think you're doing?
My voice was low and cold, surprising even myself. Guest looked at me with a bewildered face. But my eyes were already fixed on that stranger.
A similar face, familiar gray eyes, and a smile more relaxed than mine. For some reason, that smile was maddeningly irritating.
As if—he knew me well, like someone who knew everything.
