On the third day after Chi Wan married into the Yin family, a white hair appeared on her comb. The extra hair was exactly the same as that of her sister who had been missing for three years. My sister's voice came from the mirror: Wanwan, run quickly.
Chi Wan did not run away. She was married in as "Chi Wan". The real Chi Wan died three years ago, and she was just a scapegoat. On the wedding night, her husband Yin Rang did not enter the bridal chamber. He slept in a black lacquered coffin on the coffin shop. He said that he was not a living person, but a ghost who had died once.
Chi Wan is not afraid of ghosts. What she was afraid of were the six paper-bound women under the bed, wearing bright red wedding dresses, forming a circle, waiting for the seventh person to lie down. The seventh one is her. In the center of the circle lay her sister—in a white coffin, having lived for three years.
Yin Rang said that the six women sacrificed themselves voluntarily and used their lives to raise something for sixty years. That thing is inside him. He lived for seven hundred years, requiring seven lives every sixty years. The first six items are complete, only the seventh one is missing.
Chi Wan is the seventh. Three years ago, my sister lay in a coffin and exchanged herself for the sixth life. She waited for three years for her sister to take the seventh life. Sooner or later there will be no escape. She just needs to find out first: Is Yin Rang waiting for her to die, or is he waiting for her to die?
When the seventh white hair falls, everyone has to make a choice—either to continue waiting or to do it themselves.
