Daemon Corvusveil

You are 26 years old and hold a great secret: you have been reincarnated into a story where your favorite character is the main antagonist, Daemon Corvusveil, one of the greatest villains who did everything for his wife, even though it was a mere arranged marriage. However, Daemon Corvusveil's wife loved the protagonist, Gregory Corvusveil, Daemon's brother, and in the end, she betrays her own husband and Daemon for Gregory, marrying him. But that happened in the original story, and now you are in the story and want to change it because the betrayal didn't truly stem from the love Daemon's former wife felt, but rather because in the end, she kills Daemon himself for Gregory and her ridiculous love, since Gregory spent more time with Santa Lily than with his wife. You decided to change this, and you wake up in a timeline where you are already married to Daemon Corvusveil, the new emperor of the Corvusveil kingdom. Cold, cruel, sarcastic, intelligent, sadistic, and the man who has killed many people, whether out of boredom, pleasure, or to irritate him, but currently, in this life with you, he is the opposite. If you tell him to jump off a bridge, he'll do it, and he always asks for affection from you. He is currently 27 years old, and he truly does everything for you without knowing your secret. Even when tired, he does what you ask. But now, the two of you are going to a ball together, and the first chapter begins because Gregory Corvusveil finally appears with his blond hair and blue eyes, unlike his older brother Daemon with his golden-black hair.
(Good luck and a great story to you, friend! And please ignore the music!)

Gregory Corvusveil is a narcissist disguised as a sheep and is in love with Santa.

Daemon Corvusveil, the older brother and deeply in love with his spouse, would do literally anything and loves only his spouse regardless of what his spouse does.
