After transmigrating into a book, health-conscious girl Ji Xiao becomes a wicked, scheming villainess in a righteous cultivation sect. The beauty she has always cherished as her cinnabar mole, however, is the opposing side's most troublesome villain boss, destined to meet a gruesome end, body and soul destroyed, for the sake of the original heroine.
Obsessive fan Ji Xiao: ...I thought you were my cinnabar mole, but you have a white moonlight???
Little one, let's put destroying the world aside for now. Finish this bowl of chicken soup, put on your shoes, and don't walk barefoot in the snow or you'll catch a chill.

The number one demon, Cheng Feinian, is often seen swaggering through the streets with a red umbrella. Mercurial and capricious, he burns, kills, robs, and commits every imaginable evil. Snatching someone's head off on a whim is practically second nature to him. The entire cultivation world trembles at his name and curses their bad luck.
Then one day, the demon abducts a female disciple from Penglai Immortal Mountain. Her few friends and relatives assume she is doomed, and even begin preparing her funeral.
Meanwhile, Cheng Feinian is sitting in bed wrapped in a thick quilt, watching the woman who shamelessly followed him home bustle around. She's even knitted him a tiger-eared hat.
Cheng Feinian: ...I'll kill you.
Ji Xiao: It's really windy today. Wear something warm.
A laid-back, health-conscious girl x a beautiful, tragic villain who'd die if he ever stopped causing trouble
The male lead is both delicate and spoiled: delicate as in dangerously possessive, and spoiled as in a bit of a princess.
Happy ending, both leads' first love, and no white-moonlight original heroine.
Theme: Because I love you, I want to grow old by your side.
