Just like the Sleeping Beauty in Children's fairy tales, who must receive a magical kiss from the Prince, her true love, in order to wake up from the curse.
Likewise Arthur, he needs his Mate, his soulmate, his true love to help him wake up from the magic that shackles him.
And Arthur's Alpha Mate turns out to be an innocent girl.
Like reading teenwolf, basically same plot so far, allison the girl in the film is like xin, in the film he has to control his heart rate to stop turning into a wolf, he plays hockey to impress the girl, in this case rugby?
