Chloe always thought she was just a quiet girl with a complicated family-until her birthday party changes everything. Raised by mafia boss Don White, she discovers she was adopted not out of love, but for a reason far darker: a red, heart-shaped birthmark on her neck. According to an old legend, whoever takes her virginity will gain control over the underworld. Drugged and nearly assaulted by her longtime boyfriend Ken under Don White's orders, Chloe manages to escape-running straight into the arms of Don Leonardo, a powerful and mysterious mafia leader. What starts as a moment of survival becomes something much deeper. Unknowingly, the two share a forgotten past... and a spark that neither can ignore.
