I, Hogwarts' Second Loop

After being ravaged by the extremely 'correct' world of Harry Potter, Owen successfully initiated his second loop of Hogwarts.Along with the mastery of magic and memories, he, with boundless arrogance, is about to step into a brand new school life.If you don't like someone, hit them! If you don't understand something, just charge forward.Want to ask why he's so tough? In a word, I'm the most beloved treasure of my grandparents!(ps: A brand new story, not following the golden trio. Just want to write a story about a 'happy' little wizard, if there are any problems, don't argue, it's all the author's fault.)
