As a child, Meng Hui was involved in a terrible accident. Though she has born the physical scars of that moment on her face all her life, it’s the mental scars that have caused the greatest damage. Traumatized by the event, Meng Hui developed a dissociative identity disorder which causes her to switch between two distinct personalities at random. Never knowing when her alternate personality might emerge, Meng Hui has struggled all her life, to find a balance between her two sides. Now grown, Meng Hui works as a makeup artist who has started creating her own small line of homemade cosmetics. As fate would have it, she happens to cross paths with Shen Yi, the CEO of a large cosmetics company, during one of her episodes and suddenly declares herself to be his girlfriend.
