Clara, sole heiress to the empire's grandest merchant house, crowned her perfect life by marrying Fifth Prince Theo. Just one year later, Theo demands a divorce, and Clara catches him in an explicit affair with his mistress right in the adjacent opera box. Crushed by his betrayal, she is steadied by Icarus, her strikingly handsome escort. To shatter her cheating husband's ego and regain control, Clara offers Icarus a risky deal: a fake relationship under the strict condition that neither of them falls in love. However, their dangerous pretend romance soon sparks real passion that no contract can contain.
