OK some of these have my personal head cannons, so here are my reason 
Carter : before he never once had a Kit-kat, so when Leila gave him one, he ate it like that, and she just gave him a glare, but he didn’t understand why, so he just continues to eat it like that and the others find it too funny.
Leila : is it the way it should be eaten. Why? Because I personally had a canon her to be more updated on trend, considered socially good  despite being an outcast herself (magggic)
Theo : same with Lelia but I headcanon him to have unhinged or gray day every blue moon and when those days happen if he decides to eat a Kit-kat that day, he’s gonna eat it like the second option soooooooooo
Ridley : she really doesn’t care in my opinion so she eats it the quickest, or most efficiently whatever that is from the top or from the side after all, she’s tired and she wants to get it over with.
Olly & Izzy : I don’t think I need to explain.

The first chapters out!!
Alright I had this idea a while ago.
So there's the normal Hanahaki diseases. That one where if someone loves someone, they'll throw up flowers growing in their lungs until the person loves them back and that's basically the only cure.
Well I had the idea to turn it into a platonic "looking for a family" sort of situation. I thought of this at like 3 am one night and it hasn't been able to leave my brain alone.
Basically I'm working on a story where Carter Locke has Hanahaki and it only gets better when he finds a family that's not a crappy manipulative uncle. It's following pretty closely to what actually happens in the first book with some minor changes here and there.
I named it "Roses are the Flowers of a Magician" (RATFOAM for short. It wasn't intentional but I think it's funny).
