Me, second week of Hogwarts

After being devastated by the extremely ‘correct’ world of Harry Potter, Owen successfully started his second week at Hogwarts.
With his mastery and memory of magic, he is about to enter a new campus life with infinite arrogance.
I’ll beat you if you’re unhappy! Be reckless when trouble comes.
You have to ask why it is so hard! In a word, I am my grandpa and grandma’s favorite treasure!

(PS: A brand new story, it does not follow the three little ones. I just want to write a story about a ‘happy’ little wizard. If there are any problems, please don’t argue, it is all the author’s fault.)
