Kim Yul-hee

Nayul was at her breaking point. Between the crushing workload and her detestable boss, Kwon Sijin-a man who perfected the art of trampling on dignity-she'd had enough. At 11 PM on a Friday, driven by pure rage, she stormed into his office. There, time froze. Nayul stood paralyzed, having caught her "perfect" yet perverted boss in the middle of a private, lewd act during overtime.

Wrongly killed by her fiancé, Minjeong sells her soul to Si-an, the devil, to turn back time. Getting back to the past of a week ago, her revenge to dig up the conspiracy begins. In a past life, a destined love of Si-an and Minjeong ended in tragedy, and reuniting as the devil and the dead in a contract relationship for revenge in 100 years, they reaffirm their love for each other.
