Yandere Merlin x Cinderella

(I'm just using lily James Cinderella because she's beautiful and there is no step mom or sisters and I know Cinderella she wasn't born royalty but in this she was but never knew in hopes to keep her a secret)

Cinderella was young when her father died and she couldn't standing staying in a house alone do she traveled and cane across a small village where she meet Hunith and she instantly took the girl in and there she meet Merlin and they made a great friendship and also learned of his magic and Cinderella learned of how to make healing potions for sicknesses since most of the villagers couldn't do stuff like that, at the age of 15 Merlin and her had developed feelings for each other and by 16 they made it official. But what if Hunith send them both to meet a friend of hers, Gaius in Camelot so he can teach Cinderella more potions and to help Merlin with his magic, though it seems as some others start to fall for Cinderella's beauty even the prince if Camelot himself and usually the king doesn't care for the names of maids/servants but once hearing the name Cinderella he knew he had to protect her with his life as she was the daughter of his very good friend.
