The Day He Told Them

Harry is a little, and he's known this for years. Only, he never told anyone, and no one suspected that the Boy-Who-Lived could ever be a little.

When Harry finally tells Hermione and Ron that he's a little, Ron is supportive of him and researches everything about littles to further support Harry. Hermione, on the other hand, is unsupportive, telling him that it "wasn't natural".

One day, Harry stumbles across Tom Riddle and happens to fall into his little space.

It all starts when Harry Potter, Boy-Who-Lived, calls for his dada.
