Dirty Business Vol. 1 (novel) - Dirty Business, #1

A destitute woman. An unrefusable offer. A past left unresolved. After spending three years in a relationship with Shin Woojin, Seo Hyein realized that he had destroyed her future. She's been expelled from high school, left unemployed, and hindered from attending university. Unable to fix her life and feeling powerless, she strove to take control the only way she could think of and left Woojin. Eight years later, she finds herself at rock bottom and desperately in need of money to care for her sick sister.
An unforeseen encounter brings her face-to-face with her old love and bestows upon her an opportunity. Woojin, seeking to appease his family, suggests they enter a contractual relationship that promises to benefit both of them.  Trapped in a whirlwind of memories and emotions, she eventually accepts his proposal. Has Hyein signed a deal with the devil and willingly entered into a gilded cage? Or did absence make the heart grow fonder? Honesty may be the only way to deal with this dirty business.
