Harry Potter

(I took the idea from TT)
Draco Malfoy had loved blackmail since childhood. The phrase "My father will find out about this!" had always been his signature line. It worked perfectly: he got everything he wanted. Now the aristocrat had an even more powerful attribute.

"My husband will find out about this!" was ten times more terrifying. There wasn't a single person in the entire wizarding world who didn't know the British hero, Harry James Potter, much less how fiercely he protected his companion.

When it came to Draco, every phrase about him had to be repeated a thousand times in the interlocutor's head before he opened his mouth, otherwise there would be no trace left of the room in which it was said.

It was a normal workday at the Ministry of Magic. Draco was lingering after a Wizengamot session when one of the young officials blocked his way in the corridor.
"Malfoy," he drawled with an unpleasant grin. "You do realize that your last name no longer means what it used to?"
Several nearby employees slowed their pace, becoming interested in the conversation.
"You're getting away with too much. You think you can get away with everything just because you're Potter now?"
The official approached and took the folder with documents from Draco’s hands without asking.
"These papers will remain with me. You'll return them when you learn to speak normally with Ministry employees."
A hushed whisper echoed through the corridor. Someone clearly sensed trouble was coming. The man smiled smugly, clearly expecting Draco to back off.
— Well? What are you going to do now, Malfoy? Run and complain to your famous husband?
The corridor became suspiciously quiet.
