Anastasia Inara Lucero is a cheerful college student who loves making people laugh. She's loud, funny, and kind to everyone she meets. But behind her bright smile is a painful family life she hides from everyone. To escape reality, she finds comfort in reading novels. One day, she buys a newly released novel called The Unwanted Tyrant's Wife. What catches her attention isn't just the title, it's the woman on the cover, who looks exactly like her. The woman is a side character, the duke's first wife, who is destined to die in the end. On her way home, Anastasia saves an old woman from a speeding truck. She dies, only to wake up inside the very novel she just bought. But there's one huge problem. She didn't become the heroine. She transmigrated into the unwanted wife of the empire's most feared tyrant duke, a woman destined for a miserable ending. Can Anastasia survive her cold-hearted husband, change her tragic fate, and rewrite the story before it's too late... or will she become the forgotten wife history was meant to erase?

She died once. That should have been the end. But instead, she woke up in another world. A world ruled by magic. A world where power decides your worth, where the strong are worshipped, and the weak are nothing. In her first life, she was an assassin. A woman so formidable that no one dared to touch her, her presence alone enough to silence a room. In her second life, she became a princess. Not just any princess, but her favorite side character from her favorite manhwa. The problem? Nobody liked her. The character was hated, mocked and called useless. Her reputation was ruined, simple because they called her as an attention seeker, cruel, obsessed with a man that was forced to marry her. The princess was the weakest in a family of monsters. A royal who, they said, did not deserve the crown. That was the reason why the princess died. Will she accept the destiny of this princess? Or will she let her die again, just as she did in her first life? Or perhaps, she will become the key to unlocking the hidden power the princess has carried all along. Something dangerous. Something powerful. Something that could change everything. This time, she will make sure to take revenge. To rewrite the fate of her favorite character, even if she was only a side character. Will she rise and claim the power that was meant for her? Or will this new life destroy her before it even begins?
