I worked as Gu Chengze's stand-in for three years and kept his Bai Yueguang photos spotless.
On the day Su Wan returned, he pushed me down the stairs with his own hands: "It's time for you to get out."
Later, I blocked a fatal knife blow for him and heard him shouting my name heartbreakingly.
When the operating light came on, I smiled and said to him, "Gu Chengze, this time you are watching my back."
