It's so great to find a new fandom you're enthusiastic about! I know the feeling of sort of flirting with fandoms but not really wanting to stay for long. HP is for me too the fandom I keep going back to for some reason, even though I really don't like the canon anymore. It's weird, there are so many canons I love way more than I ever did HP, but still I don't necessarily feel that fannish about them.
