A sacrifice to the devil, Min Sohee, was just a young doctor who loved to help the ones in need. After her sudden death, she was led into the underworld and became the sixth wife of the devil, Jung Hoseok. He held her heart, listening to its beating as if it was music. She didn't have his heart in return. All she got were his cold responses and demands. In his eyes, she was one of his wedded wives. In her eyes, he was her everything. "...aғтer all, yoυ've вeen dancιng wιтн тнe devιl all along."
