对一个人最狠的报复，就是这两个字，这才真的解气

The passage discusses the idea that the most effective revenge is not actively seeking retaliation, but rather moving on and living a happy life, demonstrating that true revenge comes from inner peace and not getting caught up in anger or resentment. The story of the couple serves as an illustration of this concept, where one partner chooses to let go and focus on their own well-being after a betrayal.
