To save my friend, a masked man forced me to spy on a mafia heir. But what happens when my target is the only one who protects me?

"You're just a worthless Omega!" Her fiancé pushes her away for the Silver Fang princess, unaware that she is the true heiress of Frost Fang, undercover for three years to solve her mother's murder. In her darkest hour, a mysterious man appears, claiming to be her father's subordinate. His strength provides her shelter, his gentleness offers her comfort. But as she suggests a fake marriage alliance, she realizes she's already fallen into the Thunder King's sweet trap, one carefully laid with tenderness and protection.

I clawed back from death's edge, my baby's killer smiling above me. Now my scar's gone, but the betrayals remain. Will vengeance save me... or destroy what's left of my soul?
