After her mother died of illness, Su Qingyan, an unpopular concubine in the Su family, unexpectedly awakened the ability to "listen to the heart" and could hear the truth in other people's hearts. Her aunt, Wang, appears to be compassionate, but in fact she plans to send her to a remote village; her aunt, Su Mingshu, secretly stuffs dirt into her room in order to steal her engagement. Qing Yan used his mind-reading skills to see through layers of conspiracies - first exposing his sister's "stealing" drama, and then using the personal evidence of the Wang family's affair with the foreign concubine to force the Wang family into chaos. Finally, at her father's birthday party, she publicly exposed the truth about her aunt's mistreatment of her concubine for many years, completely changing her status in the family. She even unexpectedly heard the hidden secret of Pei Yanzhi, a new scholar in the family, "I won't marry him unless I am her."
