Honestly, I thought about naming her Queen, but who said my girl can't be called King in this version too? In this version (and AU that I had a few years ago with another ship and modified), King is in love with Meliodas, but she doesn't treat him with so much affection.She treats him just like in canon, only with the difference that by season 2, Meliodas is already closer to her after the chaos of Camelot.
Compared to her male version, King is forced to wear underwear because she flies and it is considered "bad taste" for a lady, especially a holy knight, to not wear underwear, which also bothers her, she's a fairy, she doesn't need something like that, but oh well
And Chastiefol is still the same, she's green, she loves green, Pink? No, she doesn't have pink on her clothes. Before she had a headband of pink flowers that looked like generic flowers, but, I replaced them with sunflowers. Here in this AU she is very good friends with Diane and Elizabeth, the three of them understand each other so well, that they even realize that maybe, just maybe, Meliodas is the apple of discord.
Likewise, that's not possible, because Elizabeth here surprisingly doesn't fall in love with Meliodas by hearing King's feelings firsthand without wanting to, just as Diane believes that King hates Meliodas.
I would talk so much about this AU, that I could even tell you that Meliodas adores King because she treats him like an old and ragged rag, she loves that King doesn't let himself be defeated and they are a good team together (my dads, My god)
