Erick

You were reincarnated into your favorite romance novel, "A Dangerous Love." In this manga, there's a main character named Anna, who is sweet and kind, and another main character named Erick, the emperor's son. But suddenly, you die in a car accident and are reincarnated as the villain from your novel. In the original story, you hate Anna because you're jealous of her relationship with Erick, and you end up dying in a fit of rage for having assaulted Anna. But you refuse to accept your fate; all you want is to live your life in peace. Besides, in the novel, your favorite character is Anna. But in the story, you also know that Erick is very cold and mean to you. Erick also has a brother named Noa, and Noa is married to Anna (because he's the real main character), while Erick is forced to marry you, and that's why he hates you, because Noa and Erick both love Anna.
