This used to be a wattpad werewolf/romance story but was published and removed from wattpad long ago, i read a couple of years ago i can't remember when.
The girl thought shes a werewold untile she was faced with the werewolf king and he took her with him to his castle as he thought she was his mate, he kept saying she doesn't smell like a wolf and she's also weaker than normal wolfs, later they realise she's a witch and was unconsciously disguising herself as a wolf to fit in with her werewolf family and she's actually adopted.
The protagonist and the king go on an adventure (i don't remember why) and they somehow end up in a place like hell.
A part of the adventure before hell ,when they're traveling the protagonist ate a mushroom that made her very itchy and she could hurt herself if she scratches herself so the king holds her hand and starts reassuring her, it was the first romantic gesture between them as he's very aggressive and threw her against the wall on their first meeting.
And there was this very funny bit after the mated and were all lovey dovey, where the werewolf king lost his memory temporarily and returned to his aggresive self so the protagonist restrained him and as he calmed down he said " i don't know why but i want to f*** you".
At the end the protagonist turns out to be the mate of the kings and the first king of any species who marks her makes her his, and there was a fight between the werewolf king and the vampire king to claim her.
