Daisy Loveletter ( Birthname Daisy Petal ) is an earth pony that comes from a family of florists. Their cutiemark was misinterpreted by their parents as a romance writer, however the writing they got their cutiemark from was not a romance at all, which made them confused with their own special talent for years.
Their special talent is actually a fanfic writer - their cutiemark representing the love they pour into their writing for the original source material
I have no clue what their gender deal is
