I noticed something in all of MXTX novels.
The characters, Hua Cheng, Wei Wuxian, and Luo Binghe. They all fell off something in thier life.
Example Wei Wuxian fell off a cliff. (Voluntarily fell off)
Luo Binghe fell off a cliff. (Was pushed down Honestly)
Hua Cheng fell off a building (In his younger years, when he was a child)
One thing is, only one off them was saved, can you guess who?
