In a car accident, Chen Yue's life changed drastically. The first half of my life was hidden in disappeared memories with no place to explore, and the future of falling into the confusion of amnesia is far away. She cautiously tried to right her misaligned life. But discovered it accidentally. The scenes of gentle and delicate care were just a show on occasion; the sweet and beautiful memory scenes were all mirrored. The nanny with a weird attitude and the suspicious boyfriend coldly pierce the mask of reality. Close friends, passers-by, doctors, and police came on stage one after another, disrupting her only cognition. Doubt and trust are separated, truth and illusion coexist. The car accident a year ago gradually came to light, but there was still no trace of the Christmas Eve in the dream. Chen Yue began to doubt everything in existence: Who is the doctor? Who is the boyfriend? Who is she?
