When legal beauty Ouyang Hong represents a trade secret case, she accidentally discovers that the upstart technology man Zheng Mengqi in the dock is actually a suitor she rejected in college. The former young computer science senior has transformed into a cold-faced Shura in the business world, and the merger and acquisition plan she proposed in a desperate bid to win the lawsuit coincided with his business plan that had been brewing for ten years. During the tit-for-tat game on the negotiation table, Zheng Mengqi discovered that the returned love letter contained undeciphered Morse code, while Ouyang Hong smelled conspiracy in the evidence chain. When her rival's fatal evidence pointed to the Zheng Group, she acted as a defense lawyer under the pressure of public opinion. However, during the confrontation in court, she received an anonymous courier - the yellowed envelope contained the source code of the dating social platform that the two designed together twenty years ago. In the fog of business war, two hearts bound by interests run in both directions in the puzzle of the truth, and the real enemy is holding the time bomb planted when they were young.
