So this random black girl turns out to be this super ultra powerful wizard.
Her best friend is a ftm asian. There is hints of a budding relationship between them.
Harry is older now and hates magic. He says magic is a mistake and all wizards must stop using magic and become like muggles.
Long story short, Harry is revealed to not be the true horcrux and Voldenort returns to admit the new random black girl star is actually the ultimate horcrux and Harry's adventure was all pretend so he could bide his time.
She obvious kills Voldemort once and for all and Harry says she is the true potter and resigns his name to her.
and for no reason the asian dude is kinda dropped as in never goes anywhere and romance never happens
