I’ll do anything if you can just lend me the money!"​Back in high school, Kate Thomas had it all—popularity, beauty, and a cruel streak. Her favorite target? Xavier Sterling, the quiet, stuttering nerd she relentlessly clowed and humiliated just to fit in.​Fast forward six years. Kate is completely broke, her family is facing immediate ruin, and her mother is fighting for her life in the ICU. Desperate for a miracle, she walks into a luxury penthouse suite to beg a ruthless billionaire for a loan, only to find herself staring into a pair of familiar, ice-cold eyes.​Xavier is no longer the broken boy she crushed. He is now a devastatingly handsome, multi-billionaire tycoon who has built an empire out of his past trauma. He agrees to clear her debts tonight on one condition: Kate must sign a 365-day contract to become his fake wife to fulfill his father's dying wish.​But Xavier has a deep insecurity—he believes every woman only loves his wealth, never what’s inside. For the next year, he plans to study her every habit, every smile, and every move under a microscope to see if she's truly changed or just playing a game.​Can Kate survive a year in the lion's den with the devil she once created, or will his thirst for vengeance burn them both to ashes?
