My best friend secretly exchanged her child with me, thinking that I didn't know about it, but in fact I had already exchanged the child back without her noticing. Eighteen years later, my best friend's daughter came to me and thought I was her mother. I had no choice but to ask for a paternity test. Only then did I find out that my best friend had been abusing her daughter. On the day when the test results came out, my best friend came to my house and denied that it had exchanged children and completely forced her daughter to death. When I told her the whole truth, she realized that she had killed her daughter with her own hands, and she went completely crazy.
