Shen Ling'an, a court lady who was framed and died tragically in her previous life, was reborn as a low-level fire girl who just wanted to survive, save money and run away.
It happened that Rong Yan, a crazy tyrant who suffered from the terminal illness of "overloading the five senses at night and losing control", was accidentally bound to a "mind-reading skill" that could only hear the heroine's voice in one direction.
Shen Ling'an looks cowardly and respectful on the outside, but is crazy and venomous in his heart. This contrasting "heart noise" turns out to be Rong Yan's only life-saving antidote.
So Rong Yan was scolded expressionlessly while frantically creating opportunities for Shen Ling'an to make medicinal meals for him to prolong his life.
Shen Ling'an unknowingly "tamed" the tyrant with her cooking skills and her inner voice, and with Rong Yan's secret escort, she used her past life memories to kill everyone and send her enemies to hell one by one.
