There Is a Little Badger in HP Fandom

The writing is incompetent. To put it simply, it is a story about a time traveler who traveled to HP and then entered Hogwarts to observe the excitement and gossip. PS: The CP is undecided. I personally prefer the professor, but I don't have enough poisonous tongue skills, so I am hesitating. Simply because I read too much HP fandom and then dreamed about it in the middle of the night. My hands were itchy and I wanted to write it down. The writing is not good, there may be bugs, please criticize and correct me. It belongs to the mediocre series of running accounts, and its abilities are really limited~
