This story is about Harry Potter having a mental illness.
"If we interpret the story as Harry's fantasy, then the Dursleys are Harry's real parents, and the Potters are imaginary. The Durselys either can't cope with the increasingly-delusional boy living with them, or perhaps they are merely abusive, and it's the abuse that's making him delusional. In any event, the parent-figures constantly mistreat him, favor the brother, and inflict endless cruelty and humiliation on him. One day, Harry snaps, and Dudley (who is really Harry's brother) is severely injured, in a way requiring repeated hospital treatments. (In the delusion, Harry imagines that a pig's tail is magically grown from Dudley's buttocks.) As a result of this incident, Harry is taken away to a "special school." This comes from a theory from a reddit user called, u/Mr_Broomstick nine years ago, but I decided to take it up a level and bring this theory to life via story. I hope you enjoy it.
It's the 1st story of the Harry Potter series but with a different idea I've been working around of the story. What if instead Harry lives with the Dursley's, a ex-dark witch wants redemption and takes in the child as her own? What if Harry and Draco got along as children and even are cousins? What if instead of being friends with Ron Weasley, he and Draco befriends Hermione Granger and Pansy Parkinson first? All of this will be answered in this story.
