My Best Friend Secretly Replaced My Daughter and Reaped the Consequences

My best friend and I gave birth to our daughter in the hospital at the same time. She secretly switched the two children. I saw it but didn't step forward to stop her. I took good care of my daughter and raised her to be a talented person. However, my best friend beat and scolded her child frequently and abused her in every possible way. It wasn't until her daughter's coming-of-age ceremony that she came to me with her daughter, who had been tortured to the point of death, and said, "The nurse made the wrong mistake. The one who is dying now is your daughter, and the one who is about to become an international pianist is my daughter!" Looking at my best friend's proud and vicious eyes, I also smiled.
