I Came for Revenge, So How Did I Become Everyone's Favorite?

Chen Amei was a yellow weasel who had cultivated for three hundred years. One fine, sunny day, she decided to ask a passing human to grant her a title.

As a result, heavenly lightning struck her and destroyed her body. She flew up to Heaven in disgrace, then stormed off to seek revenge from the Star Lord Siming, only to be told that the descendants of the man who had wronged her were fated to become villains. As it happened, she could descend to the mortal realm as a vicious supporting female character and personally take down those descendants.

Chen Amei rubbed her hands together and cackled excitedly. Without a second thought, she accepted the mission.

But... why had she come to exact revenge, yet everyone called her their darling?
