Invalid Substitution

When I was five years old, the little girl I was engaged to was born. I went to visit with my family, but found that she was in danger. I quietly stayed by her side and protected her. Many years later at the engagement party, the family's former nanny suddenly rushed out, pulled a girl in front of her, and made a scene in front of everyone. She said that the person in front of her was the real daughter of the Song family. The faces of both parents changed drastically, but I spoke calmly. I had always seen what happened back then. From then on, I protected the people I wanted to protect. Mother Wang, this person beside you is your child.
