5-Year-old Xia Nuo was abducted by a trafficker. At the critical moment, she bit the trafficker and ran away. She was rescued by her aunt and cousin and called the police. This incident gave her nightmares every day, and she couldn't remember the details. She only remembered that she ran away after biting the person, and she didn't see what the other person looked like.
The police searched the scene and arrested people, but could not find anyone with bite wounds. Combining Xia Nuo's statement and the gang's confession, the police knew that there was a mastermind behind the incident named Lao Jin, and concluded that he was the one who was bitten. But there were too few clues, and the case became unsolved for decades.
After Xia Nuo disappeared, her father died unexpectedly while looking for her, and her mother couldn't bear the shock and left. She had lost her parents since she was a child, and was sensitive and afraid of blood. Fortunately, her cousin's family took care of her, and she slowly came out of the shadows.
In 2006, she went south to work, and a year later she met Cheng Mo. He is the first person besides his family and best friends to truly protect her. They liked each other, he kept the watch she gave him, and she wore the silver bracelet he saved up for several months to buy.
Later they were separated. After leaving, Xia Nuo concentrated on his career. After his career became successful, he specialized in charity work to rescue abducted children. Cheng Mo drifted away for many years and fell in love four times. Finally, he returned to his hometown and got married, hiding his youthful love in his heart.
They met again many years later, and the tooth marks from that year were discovered, which led to Lao Jin and experienced many dangers. But in the end, they were still not together, they just smiled at each other and lived their own lives.
