She was once the daughter of the Lin family and the "mistake" that the Shen family avoided.
She is an abandoned baby, an illegitimate daughter, a pawn of a wealthy family, and a system experiment subject.
Her name is Lin Xi, also known as Y. X - a code name that no one has ever really called.
Starting from a carefully arranged fate, she was thrown into this world and learned to be silent, know how to show weakness, and get used to saving herself.
But she refused.
She wants to tear off the labels, cut off the control, destroy the system with her own hands, and live the way she wants.
"You think you are a miracle that has derailed, but in fact, you have been on the track."
"Then if this track is wrong, I'll - blow it up."
The love and calculation between adults, the tearing and reshaping of fate, secret love, pulling, misunderstanding, betrayal, heartbeat, reunion...
She is no one's daughter, no one's salvation.
She is Miss Xi, a traitor to fate and her own hero.
