Su Wan, a daughter of a wealthy family, was pushed off the rooftop by her stepsister on the eve of her wedding. Her soul was reborn as a ragdoll cat and she was adopted by business tycoon Gu Chengze. In the process of searching for the truth about her death, she discovered that the mysterious man who saved her in the rain three years ago was actually Gu Chengze, and the dusty organ donation agreement in the other party's study pointed to a deeper bond between the two. When the moonlight gives him the ability to temporarily transform, misunderstandings and sadomasochism caused by his dual identity intersect with the battle for the inheritance of the Gu Corporation. In the end, in the process of solving the serial conspiracy, the cause and effect reincarnation of the Su and Gu families spanning thirty years was revealed, and two-way redemption was completed using the technique of soul symbiosis.
