Jiang Mian becomes the contract wife of the villain in the book, and her mission is to prevent him from going dark within three years. She originally thought that she could escape safely as long as she stayed calm and gained favor, but she didn't know that every "care" she expressed was remembered by Xie Yan. When the favorability level finally reached its full limit, she realized that she had been trapped by him - not just a contract, but all of his paranoia. A story about "I thought you were acting, but in fact you were acting my heart".
Purpose: Sincerity and companionship can resolve indifference, and love is a two-way cure.
