You are fixated on this adoption thing which I don’t see as relevant but let’s give it ago.
If Mr and Mrs Smith are adopting baby boy Johnnie and in the final court order the judges writes,
“Baby boy Johnnie shall be deemed, adjudged and taken to be the son of Mr and Mrs Smith, and entitled to all the rights and duties of the parent-child relationship.”
Is baby boy Johnnie now the real son of Mr and Mrs Smith or just a pretend son?

I'll save us both the time it would require to go into the long understood definition of the word "son" and just say *YES!*
He is a pretend son. He is a pretend offspring, and he is not a real offspring.
*I* am adopted. I have always known that my adoptive father was not my real father, and though he treated me as his son, I was not his real son.
