Hogwarts: the Seven Sins Pact

How would the whole story change if Harry became Harley? After the mysterious man fell, a prophecy spread secretly: ——A demon king of seven sins will appear in the world. ——Beautiful, powerful, immortal, immortal. ——He will turn the whole world upside down. ——Only the magic of love can stop it. On an ordinary morning, eleven-year-old Yas Revan was looking at the parchment in his hand with a confused expression: "I am willing to take over the authority of the seven sins and carry out the name of the seven sins of arrogance, jealousy, wrath, sloth, greed, gluttony, and lust - Contractor: Yas Revan" Yas stared at the parchment in his hand, feeling confused. Shouldn't it be the acceptance letter to Hogwarts? Why did it suddenly become the Seven Sins Pact? In order to protect himself, he decided... Harry Potter, right? The Boy Who Lived, right? The savior who is destined to defeat the Demon King, right? "Harry Potter! Eat me..." Yas's movements froze. There was a girl sitting in the carriage. She was thin, with black hair, a pretty face, a lightning scar on her forehead, wearing round glasses, and a hint of confusion in her emerald green eyes. "Hello, my name is Harriet Potter." The girl held out her hand. On one side is the legendary girl savior, and on the other is the prophesied Dark Lord of the Seven Sins. Professor Snape's cold breath suddenly came from behind, and Yas put away his wand silently. (Harem story) (male protagonist story)
