I Transmigrated as the Villainess, So Married Duke Who Was Supposed to Kill Me: Book 1: A Winter Wedding

She said yes to a proposal on a subway platform. She woke up engaged to a man who murders her in the book. Marielle just wants to go home. Instead she's trapped in the body of a villainess she's read about a hundred times, three months from a wedding night that ends with a poisoned rose and a very dead bride. So she does the only thing that makes sense: she marries the Duke instead of the Prince. He's cold. He's dangerous. And in the story she knows by heart, he's the one who kills her. He's not supposed to fall for her. She's not supposed to fall for him. But somewhere between a garden, an umbrella, and a fifteen-year-old secret buried in her own father's ledgers, the rules of the story she thought she knew start breaking apart. There's a blade above his mantel that's waited seventeen years for a debt only her family can pay. And a wedding night is coming, whether either of them is ready for what it costs.
