The Villainess's Days are Numbered!

One moment, an ordinary life; the next, a waking nightmare—our heroine opens her eyes inside the body of Clea Rino, the most notorious villainess the world has ever known. Before her death, Clea struck a bargain with the Demon King, one that promised her marriage to her beloved, Isaac Detroi. Bound by that pact, the protagonist now has just six months to see the contract fulfilled before she can reclaim her own life. But hidden within the fine print lies a cruel catch: Clea's body is so frail that every single step costs her precious vitality—literally one HP lost with each stride. Racing against a shrinking clock and an ever-weakening body, she makes a desperate gamble, surrendering Clea's family fortune to secure Isaac's hand in marriage. On paper, it is nothing more than a cold, calculated transaction—a means to an end with no room for sentiment. Yet as the days pass, the line between business and genuine affection begins to blur. Why is her heart racing for a man who was never meant to be hers? Perhaps even the world's most wicked villainess turns out to have a heart after all.
