I'm still craving for romantic hc for my canon x oc ship and I thought of these parts of my lore regarding Charlie and Maya's romance arc xD (I wanna share it because it's all over my head for years and I'm eager to share this one)
♥︎ Charlie will be the type to fall in love first but would constantly try to let his feelings for Maya away as he thinks it will be a distraction for his love of dragons (that's why he's always saying that dating isn't his thing) while Maya would be the type who slowly falls in love with someone after a lot of interactions. Maya's first crush was Felix Rosier, her house prefect which she fell in love at first sight to him. She immediately loses feelings for Felix after knowing he has a girlfriend (my OC Esme Allard) which makes her think that love at first sight will bring her towards negative results.
♥︎ Maya has a LOT of admirers and one of them is Alfred Jones, a Gryffindor student who's a year older than Maya who won't stop courting her during her 3rd year (and Alfred being a 4th year). Maya always rejects his courtship but Alfred being too overly confident, he didn't give up and still continues on courting her. This caught Charlie's attention and jealousy starts to build up in him though he couldn't do anything to it as insecurities stop his urge to confront Alfred.
♥︎ On their 4th year, Charlie and Maya interact a lot. Always sneaking to the Forbidden Forest to find something interesting (whether it is related to the curse vaults or not) and wouldn't eventually sleep outside of Hogwarts together after their hangout in the forest which both will be found by either Bill or Malachi who are very worried for them. (Also they mostly sleep on the seats of the Quidditch pitch xD).
♥︎ The two started dating at the end of their 4th year. Charlie sent an anonymous letter along with Maya's favorite flower (moonflowers) which he stole from the Herbology Classroom. Maya being skilled at knowing someone's hand writing especially the hand writings of her close companions, she knows who wrote the letter she received. Instead of sending her answer via letter, she said her answer in person which made some students surrounding them shocked at what they've heard.
"The female curse vault kid likes Charlie Weasley?"
"Wait, isn't Charlie Weasley the one who likes Maya Avery first?"
"No wonder the two were so close"
"Poor Alfred if he hears about this.."
