Additional Likes and Dislikes (Important Note: your artist or author is not required to take these additional preferences about setting, era, tone, etc. into account, but it might help them come up with ideas, so include as many as you like. This is not the space for hard and fast triggers or squicks; those should be placed in the list of elements that you are unwilling to receive above.)
I love romance, crushes, UST, secret admirers, matchmaking, wooing, first kisses, awkwardness, first times, slow build, banter, bickering, blushing, creative swearing, coffee, tea, bottles of wine, meaningful connections, complicated/frustrating/crazy/or interfering families, adult characters, flawed but likable characters, character growth, pining, and funny.
I dislike infidelity, one-offs/one night stands, night club type scenes, sex scenes that don't add anything to a story (I.e. Gratuitous), anything very kinky (I'm pretty vanilla), Death Eaters (except Greg, Draco, and Snape), underage sex, anything really dark (angst is okay), tragic or hopeless endings
A few ideas I would love to see (but don't let me stop you if your bunnies have other ideas!): Petunia or Dudley paired with Hestia during their time in hiding. (If Petunia, I'd prefer Vernon not in the picture anymore, however works in your story.)
Millicent, Marietta, or Greg in a story where someone is trying to woo/date/whatever them and they're oblivious or disbelieving. (I'm particularly fond of Millicent with Charlie, Neville, or Viktor but I'm open to surprises!)
Pomona Sprout playing secret admirer or trying to charm a colleague. (any Professor but Trelawney or Dumbledore, please) I'd love to see flowers with meaning or wacky plants or fun mishaps.
Petunia/Vernon-- show me why/how they fell in love and make me ache for them a bit.
