Hi Guys, I finally gathered enough courage and decided to write a fanfiction about Harry Potter after so many years of reading it for free without any contribution. As a long-time fan of Harry Potter, I would love to say that...Long Hail the Harry Potter!!! This fic is basically just a self-inserted story of what if our beloved Sirius Black had a son that he didn't know about. Let me introduce you to our main character Alan Walker-Black, an orphan at birth, born 1 year before Harry and a result of Sirius's one drunk funny night with a girl that Sirius didn't even remember the name. Shall the story begin... P/s: English is not my first language. I'm 100% Vietnamese so I apologize in advance for any grammar mistakes. Please let me know if there is any.
