The Dayin Dynasty was prosperous on the surface, but in reality there was an undercurrent. The male protagonist Xiao Jingheng is the younger brother of the emperor, with the title "Zhaoyang". He holds military power but pretends to be crazy and acts foolishly. He is a dramatist on a daily basis and plots secretly. One day, he accidentally awakened the skill of "listening to the voice of the heart" and could hear other people's inner thoughts. From then on, he started to have cheats in his life. There is a well-known "face-controlling little pepper" in the aristocratic circle of the capital - Xie Zhaozhao, the legitimate daughter of the prime minister's house. She is an eccentric and thick-skinned person who is determined not to marry a man who is not handsome. However, when she sees Xiao Jingheng, her heart beats faster and she starts a crazy cheating mode. She thought she was hiding it deeply, but in fact, he could hear every heartbeat barrage clearly. "This prince looks too bad!" "Calm down! He is my uncle! But... My uncle can also be so handsome that I can break my defense!" Various conspiracies were staged in turn, such as the power struggle in the court, the queen's setup, and the prince's heir apparent. While Xiao Jingheng relied on his voice system to predict the crisis, he was almost defeated by Xie Zhaozhao's fancy teasing. The two gradually fell in love with each other through temptations and pitfalls, and embarked on a journey of light joy and happiness. "You can hear my voice, but you can't control my sweet mouth."
