Misplaced Bonds of Blood

"I finally became pregnant after my husband and I underwent over a dozen rounds of IVF.However, to my horror, I discovered that the embryo growing inside me was the fertilized egg of my husband and the family maid.They even schemed to have me disappear so that the child could inherit everything.I pretended not to know, carried the child to term, and took care of him, raising him with love and care.It was not until 20 years later that they forced me to sign a share transfer agreement by my hospital bed, along with a divorce agreement that left me with nothing."After 20 years, we finally have our happy family. You never saw this coming, did you? The child you fought so hard to give birth to is my biological son!"Even my son, without any remorse, said, "Honestly, your illness is beyond help. It'd be better for you to just die."With a knowing, almost bittersweet, smile I replied, "For your happiness, I'm willing to do whatever it takes.""
