My Daughter Called My Flash Husband Daddy

Six years ago, student Harper spent a night with a mysterious man at a masquerade ball, then saved him from a deliberate car crash, with only a pearl hairpin and the memory of a "broken moon birthmark" left behind. Six years later, Harper, now a single mother, lives with her daughter Lily, but Lily embraces a stranger named Adrian in a café and insists he is her father. To avoid an arranged business marriage and escape their family's pressure, the two sign a six-month flash marriage agreement, neither knowing that Adrian is Lily's biological father and the very mysterious man Harper met years ago. As fake DNA results, someone falsely claiming to be the one saved from the crash, a custody trap, and a kidnapping conspiracy come to light, the couple recognize each other through the birthmark, old wounds, the hairpin, and medical records. Faced with Adrian's identity as the richest man and the lies that surrounded them, Harper refuses to rely on him, instead teaming up with Adrian to expose the crimes of the wealthy family and reclaim her career, dignity, and family.
