But behind the wiles of this seductress who never ceases to amaze all who beheld her, Shengyi appears to have a secret that she cannot tell: her tale of transmigration, and the deal behind it.

But what happens one night when the cold and eccentric CEO from the rival company, Cullen Fu appears at her bedside, telling her "It's time for you to fulfill your end of the bargain"?

"Here, let me remind you who I am."
Exploring her dainty mouth with his icy tongue, Cullen shows her what it means to give her soul and her love in her deal... with the devil.
