Sideun Kkoche Nunmureul

Romance, flowers, and dates-- once upon a time, that was the perfect description of Hae-Su and Min-Cheol. Now, all Hae-Su has is the ashes of their marriage and a mountain of debt. But her world shatters completely when Min-Cheol cheats on her with a young coworker. Hurt and betrayed, Hae-Su finds herself drawn to Tae-Ha, a young man who seems desperate for her affection… and may be hiding more than he shows.
