Harry Potter: I Picked Up an Obscurus as My Girlfriend

[Harry Potter, yuri, no transmigration, Luna pairing, slow-paced, healing, with original worldbuilding]

P.S. The plot is original and probably won't have much to do with Harry and the others, though they'll appear in key scenes.

One day, a Dumbledore arrived at Hogwarts, but nobody expected her to be Sorted into Hufflepuff.

She was a Dumbledore, plain as day, yet she kept a low profile and was often timid and cautious.

It wasn't until her identity was revealed one day that everyone learned she was an Obscurus.

While everyone else kept their distance, Luna Lovegood chose to stand before her.

Liu Xing didn't know what she was: an outcast, a disaster, or a pawn.

But Luna told her that she was simply herself.

So Liu Xing decided to listen to Luna.
