I'm in Love With A Happily Married Billionaire

A woman falls in love again with a billionaire who is already happily married, and the wife turns out to be her former best friend. She is dismissed as a liar who vanished for years and now claims to be the mother of a billionaire's child. The truth is far darker: she was pushed off a cliff, left for dead, and forgotten while that friend stepped into her place. Now her memories have returned, but her daughter does not recognize her and the man she loves belongs to the woman who betrayed her.
