She was originally the most ordinary and humble girl in the countryside;
He was originally the eldest son of a great family who was destined to become a general;
She has a name but no surname, and her life is like duckweed;
He was given a noble name, but had no life of his own;
The gear of fate makes such a woman pick up the murderous sword;
Losing his name turns such a man into a bloodthirsty beast;
Falling into the "night world" that belongs only to darkness,
Only love can save each other...
