Chen Jinzhi was forcibly sent to Yongninghou Mansion to celebrate the death of his critically ill son Xie Zhiheng. On the wedding night, the two unexpectedly exchanged souls.
Chen Jinzhi, a country girl, was forced to assume Xie Zhiheng's identity and pretend to be a noble son in the Hou Mansion. She learned etiquette, dealt with elders, and covered up her flaws. Every step of the way was startling.
Xie Zhiheng, a cold-blooded young man, was forced to assume the identity of Chen Jinzhi and become the "young lady of happiness". He endured contempt, rules and physical differences, and gradually adapted from being rejected. The two went from hating each other and threatening each other to having to act together and tell each other the truth:
He taught her to be a master, and she taught him to live as "she".
In his misplaced life, he finally realized how miserable she had been;
She also understood for the first time that people who are above others can't help themselves.
The two protected each other in disguise and quietly fell in love with each other. While looking for a way to return, they dealt with the turmoil and crisis in the Hou Mansion. They finally recognized their true feelings and completed each other's growth and redemption.
