I Will Become the Tyrant's Fiancée

One day, I woke up inside the world of a romance novel I loved to read. And of all people, I became Hana—the heroine's foil who gets poisoned early in the story. At this rate, I'm destined to be killed at the engagement ceremony. To overturn that hopeless scenario, the only survival strategy I could think of was to approach Park Woo-jin, the "tyrant" crueler than anyone in the original and feared by all, and propose a contract marriage. "Make me your shield. And you'll be my hiding place." For some reason, the tyrant accepted my life-risking proposal with a quiet smile. Thus a dangerous alliance that never existed in the original is formed. But I don't yet know—whether this contract is meant to protect me from my fate of death, or whether it's merely the beginning of a far more cunning trap set by the tyrant.
