Heavy Sweetness, Ash-like Frost

The Flower Deity dies after giving birth to a daughter, Jin Mi. She
has a premonition that her daughter will suffer a great love trial, thus
before dying, she gives her a magical pill that prevents her from
feeling and expressing romantic love. This causes Jin Mi to become the
brunt of many jokes when she gets tangled in a love triangle with
Heavenly Prince Xu Feng and the ambitious Night Deity Run Yu.

Jin Mi is tricked into thinking her father died at the hands of
Xu Feng and kills him, coughing up the magic pill in the process. Xu
Feng is revived a decade later as the Demon Lord, and wages war against
Run Yu, who has now ascended the throne as Heavenly Emperor. Jin Mi is
caught between a rock and a hard place, and ultimately sacrifices
herself to return peace to the world.
