I’m the King of scrolls at Hogwarts

It was the summer of 1991, when little Louise, a boy from Old London, received the admission notice to Hogwarts.
From then on, the students at Hogwarts faced their lifelong nightmare.
Many years later, when Ms. Hermione Granger, who had already become the Minister of Magic, was asked, “What do you think of the Prince of Hogwarts?” Ms. Granger shuddered, remembering the Mimic Monster The days of being devoured, being chased wildly by the tree guards, and riding the roller coaster on Deathwing’s back eventually turned into a faint smile. It was their most carefree time.
“His Royal Highness is the greatest alumnus in the history of Hogwarts.” She and Mr. Potter, Director of the Department of Legal Enforcement, replied in unison.
Note: The heroine is not Hermione, and the original CP will not be removed.
