Su Ti, a 28-year-old crisis publicist, was forced to "take care" of her late mentor's 18-year-old genius son Lu Yan, who suffered from severe emotional cognitive impairment. She thought she had taken over a "beautiful little trouble", but she didn't know that from the moment she stepped into his world, she became the only "emotional organ" he could sense. He used morbid genius logic to design a legal domestication of the "hunter" by the "prey".
