I was Gu Chengze's stand-in for three years, keeping the dust off his photos of the woman he truly loved.
The day Su Wan returned, he shoved me down the stairs with his own hands. "You should leave."
Later, I took a fatal stab for him and heard him scream my name in anguish.
As the operating-room lights came on, I smiled at him and said, "Gu Chengze, this time you'll be the one watching me walk away."
