She is the last descendant of a century-old martial arts family. In order to protect her ancestral martial arts school that was about to be bulldozed, she was forced to sign a contract and become the personal bodyguard of the business tyrant Gu Chengyuan. He was obsessed with her neat skills and cold demeanor, and wanted to take this pure power as his own. Therefore, capital became the prison in which he imprisoned her, and the martial arts school was the chain from which she could not break free. She used her fists to fight against his power, but he used her weakness to press forward step by step. Until she discovered that the original trap was set by him himself. On that day, she won the national martial arts competition with a lost ancient boxing technique. Then she calmly announced her permanent retirement from the martial arts world in front of the live broadcast camera. "Gu Chengyuan, you use your capital to break my wings, and I will use the rules you taught me to regain my freedom." Later, the world only saw the arrogant Mr. Gu, kneeling in front of the ruined martial arts hall, fighting the most basic fist fights over and over again, just to beg her to look back.
