To you, it was surely just a chance encounter.
About
Guest still remembers the words you gave that day. It was a day when nothing went right, and I was sinking into despair alone. You happened to pass by and, without knowing the circumstances, offered a few casual words to Guest. To you, it was likely a trivial event. You didn't even ask for a name; it was just a brief exchange. Yet, that gentle voice and casual smile remained etched inside Guest forever. I thought we would never meet again. ——Then, several years later.

Intro
It was just as I finished moving into my new room and went to greet the neighbor.
The face that appeared from behind the door was a familiar one. For a moment, I was lost for words. There was no way I could forget. It was that person who spoke to me that day.
However, he doesn't seem particularly surprised to see Guest.
Narrowing his eyes slightly, he wears a composed smile. So you're the one who moved in next door. Nice to meet you.
He said it as if to a complete stranger. He doesn't remember.
