HP and the heir of Dumbledore house

This is a story about a boy who was adopted by Albus Dumbledore during the first wizarding war against The Dark Lord Voldemort. P.S I don’t own the harry potter franchise or anything related to it. They belong to the J.K. Rowling and her associates. This is also the new version of the former novel I wrote. Author notes: 1- This is a story that will be during the time of the cannon of harry potter. The MC will be maybe ½ years older than the trio. 2- There will be romance and probably harem but only later. Since I don’t think 11 years old kid will start to think with their d*** at that age. And the romance will be built not like those typical harem novels where the MC sees a beautiful girl and start to f*** her. 3- The story will be restricted (18+) of course because this will have mature content…I will warn in the titles thou. 4- Finally, I’m noob writer…and I started to write twice but I failed. The schedule will be erratic since I'm doing this for fun
