The end of the world has come and order has collapsed. Su Wan, who was betrayed and died tragically by someone she trusted in her previous life, was reborn and returned to the beginning of the apocalypse. In this life, she abandoned all innocence and became a cold-blooded egoist. She relied on her past life memories to accurately hoard supplies and build her own safe zone step by step. On the way, she rescued Lu Xingye, a young man who was as clean as a piece of white paper. Su Wan regarded him as the sharpest knife and the most loyal dog, controlling him with extreme pulling and ambiguity, allowing him to remove all obstacles for her. Lu Xingye was devoted to her and regarded her as his only god. However, just when Su Wan thought everything was under control, he discovered that the fangs of this "little milk dog" had already been sharpened secretly. In the name of love, he weaved a dragnet for her. The two sink into the sadomasochistic relationship of using, testing, and hurting each other, and finally reveal the truth that they are both avengers who have returned with memories of their previous lives. This hunt in the name of love has already begun in the previous life.
