An Yuxi, the son of an aristocratic family of seven major families, took on his mother's surname without restraint when he was young. He went to school disguised as a younger sister and met His Royal Highness Wang Youchu, the granddaughter of King Zhuang. Wang Youchu, whose identity is unknown, always thought that the person he liked was An Xiaoxi. The two people who originally loved each other became incompatible due to various reasons.
The two met again many years later, each with their own ambitions. Wang Youchu endured the humiliation in order to seize power for the royal family in an attempt to subvert the system, while An Yuxi has become a gangster with extraordinary power and ruthless methods. In order to get what she loves, An Yuxi overcomes obstacles, tears apart traitors, and carves out a path for her lover to become a king.
