There are components that make up this world that you can see, and there are components that you can't see—or don't want to see. Everyone could see Cheng Ruyun's delicate face and graceful figure, and they could see that she had the same vitality as her peers, but they could not see the obscenity hidden deep in her eyes that a lady should not have. Everyone could see Ye Jiangnan's bruises after being beaten, the wounds cut by sharp blades, and even hear his wailing and calling for help, but they could not see the secret operations behind him. These things that the world cannot see or touch are called "secrets."
