Or to find their
real parents. Because no adopted/step kid is happy with his adoptive/step parents, and can only truly be happy with his biological mother and/or father.
When they go to find their "real" parents, don't bother to make a justification other than they "just want to know".
Bonus points if they're a
real orphan because their biological parents are deceased. Because dead parents are the best kind.
And if they're alive, they must have accept their child with open arms. They're not allowed to be ashamed of leaving them behind, because that would mean they did wrong. Anyone related to your MC as their Do No Wrong genes.
Unless they're the evil half-brother, but that's another story.
