I was just a street rat, but one day, I suddenly became a Regressor?

===LINEBREAK===
Hi, this is APieceOfRock. This isn't a novel I've written, but it's an original story not posted anywhere else. I'm just a collaborator for one of my friends. Update schedule might vary since this is just a side project of his while he's working on publishing his main novel on Novelpia.
(P.S: Second year of college is killing me so I can't continue my other novels for the time being)
