In order to help her best friend recover the design company that was maliciously acquired by the Gu Group, Su Heng, a gold medal lawyer, took on a reverse lawsuit, but she confronted Gu Yanzhi, the president of the Gu Group, in court. The two went from tit-for-tat "opponents" to being forced to marry in secret because of Mrs. Gu's matchmaking. Su Heng relied on his professional skills to repeatedly turn the tide in business negotiations and family crises. Gu Yanzhi went from being arrogant and provocative to being gradually attracted by her sobriety and independence. Finally, when they exposed their competitor's business conspiracy, the two joined forces to fight back, turning from "legal opponents" to "soul mates". The most exciting moments focus on the famous scenes where the female protagonist fights back in court, outsmarts business traps, and uses professionalism to defeat the male protagonist's prejudices.
