Jiang Wan just wanted to take the money and leave and continue to be her salted fish. But on the first night she lived in Shen's house, she heard someone talking in her sleep in the next room - "Don't be afraid, I will protect you." The person who said this was the fake daughter Shen Luxi who had taken her place. Why would a person whom I met for the first time appear in another person's dream? Jiang Wan decided to stay and find out. But the more she investigated, the more she discovered that Shen Luxi's sleep talk contained a whole secret that she didn't know - that secret was related to her own life experience, to a fire nineteen years ago, and to a silver plum blossom necklace. And the girl who said she wanted to protect her was the one who needed to be protected the most.
