Why would he decide to reach out to me 4 years later?

I remember there was a time in my life, though I'm still young. I was using a dating app. I ended up meeting this guy. We hooked up, probably.. twice. He says we hanged out 4 times, though I don't remember. I just remember this guy being very clingy to me. Not wanting me to leave his apartment while he was in college. We for some reason stopped talking, and that's fine. Out of 4 years later, I get a notification that I got a message on social media. Again, I forgot this guy's name, his age, what he looks like. This guy has never popped up in my mind at all, never again. While he messaged me, he said I'm an unforgettable person.
Again, I'm slightly confused. Not interested in hooking up. He ask me if I want to get coffee, maybe a beer. Wants to catch up and see where I am in life, and I literally ignored his message right there. Yet its also like, how am I an unforgettable person?
I don't remember any of our conversations. I know people tell me I'm this kind and loving soul. Yet it's also like.. You were a damn fling back then, 4 years ago. I do not remember you, and it's cool that I don't. Without sounding egotistical, I've had people always come back to me. Done wrong or just... something.
