I'm looking for stories where a person is adopted by their grandparent/aunt or uncle and then finds out that their other family member is their real parent later in life. Ie mom is really their aunt and aunt is really their mom, stuff like that. I'd like stories where they explore the emotional side of this not just practical, though I'll read any of them. Non Platonic relationships would be cool but Platonic ones will work too. FF or MF codes are fine.
