The stories are scattered and the writing style is changeable. You can write whatever you want.
The female-dominated dynasty (fake, essentially the male boss);
Half of the fairy tale world (the story of being cut in half); the awakened female supporting character (who was tricked into falling in love by the villain); the cute (?) Witch met the indifferent (?) Vampire; the abandoned child (Ah Cuo is quite lovable)...
Good. . . . .
