Twenty-one year old Ahn Jangmi is faced with a huge problem when she begins to swim in her runaway father's debt, and huge means huge. If she cannot find a way to pay her debt off before the final date, she'll get into big legal trouble. However, a rich and not-so-sophisticated heir stumbles into her life and shakes everything up. Kim Myungsoo, who is originally set to marry spoiled heiress, Son Naeun, is displeased by his parents and refuses to marry the heiress simply because she was chosen by them. To benefit himself and infuriate his parents, Myungsoo begins to blackmail Ahn Jangmi into marrying him by telling her that he will press legal charges against her if she refuses. In order to save herself from anymore trouble, as well as pay off her current debt, Ahn Jangmi reluctantly agrees to marry the selfish, cold-hearted heir. But as the two take on a new life as newly weds, they soon begin to discover that the facade they've shown one another is not their true selves.

I didn't know what he was going to say or what he was going to do, but I was frozen still as his gaze suddenly hit mine.

"Marry Me." He spoke in a wraspy tone, his words slow and whispered. Suddenly I felt my heart fall from my chest and sink into the pit of my stomach.”
