1. Jiang Wan Ning: She appears to be the adopted daughter of the Lin family, but is actually the daughter of the family's enemy (she was adopted by the Lin family with her identity tampered with when she was a child). He has a soft personality on the outside but is strong on the inside. He has endured ten years to find out the truth about his life experience, and he has the skills of a hypnotist (he can read other people's memory fragments through contact).
2. Lin Jin: The legitimate son of the Lin family, he suffered from dissociation disorder as a result of witnessing his mother being forced to commit suicide in his childhood. Externally he is a gentle and gentle heir, but privately he is a paranoid and crazy chess player who takes pleasure in manipulating people's hearts. Classic line: "Sister, I have already understood your chess game... But I insist on overturning the chessboard."
3. The wealthy family's conspiracy to usurp the throne: The Lin family rose by annexing the Jiang family's industry. Jiang Wan Ning's true identity is the biggest secret of the Lin family.
4. Memory Cage: Lin Jin's memory was tampered with by his father since he was a child, and he mistakenly believed that Jiang Wan Ning was the daughter of his enemy. In fact, the two were each other's only salvation when they were young.
