Brief Harry/Katie, followed by Harry/Fleur or even Harry/Katie/Fleur/Daphne
Where Katie is a salt dragon of perpetual sarcasm and wit, and Harry has a stoner horcrux after the TriWizard Tournament that thinks Harry is way too tense, and he needs to learn to chill out.
Daphne Greengrass thinks Harry is doing Sillyweed on the sly and offers to help keep with a fresh supply. But why oh why is Fleur so obsessed with Harry? And why is she always travelling in a cloud of smoke?
Also, Harry can't figure out what each girl's interest in him really is.
