I’m a time traveler

I am somewhat obsessed with validating my existence. As I describe, I make sure that anything I did is impossible to obliviate, I am one of a kind though I believe we are all but I seize to prove that I am different and would always consider myself as an exception. At such point, someone wants to turn back the time where I brought him, trying and hoping that at the present time, it will the same moment he had me. Keep traveling, maybe in his dreams, it will be a puzzle, hard to phantom to keep chasing those moments, his decisions had lead him now, I left him insatiable.
