Gu Nian has possessed the special ability to see the date of death of others since childhood. When she was little, because she blurted out the dates of death of her grandfather, father, and mother, she was regarded by the whole family as a jinx who brought death to her loved ones. From then on, she was given the cold shoulder and mistreated by her three older brothers, and was forbidden to associate with her younger sister Gu Yao. Until her 22nd birthday, Gu Nian saw the date of death appear on the palm of her own hand, and she decided to leave the best memories for her family on the very last day of her life.
