Twenty years ago, a well-planned transfer of money caused the real daughter of the Gu family, Gu Lingshuang, to be sent into the dark abyss.
She's not dead. She fought her way out of the sea of blood and corpses of the international killer organization and became the "Frost Blade", a gold medal killer that frightened both black and white. She wears countless legendary vests - the top hacker "Ghost", the mysterious medical fairy "Shou", the undefeated queen of the underground boxing ring...
Twenty years later, a car accident involving the fake daughter Gu Wanrou brought the truth to light. The Gu family's parents spent a lot of money looking for a daughter, but all they found was her most inconspicuous vest: an ordinary college student.
Gu Lingshuang originally wanted to wash her hands in a golden basin and return to ordinary life. But the jealousy and frame-up of the fake daughter followed one after another, and she was forced to take off her disguise again and again.
What makes her even more troublesome is the fiancé who escaped from the engagement party - Lu Chenyuan, the helmsman of the chaebol empire. On the surface, he is cold and ascetic, but secretly he is the leader of the national security special team, and he has fought with her countless times!
When Lu Chenyuan finally discovered that the "Frost Blade" he had longed for was the child's lover who had escaped from marriage, this man who had always been a strategist panicked for the first time.
"To continue the engagement, the person must be you."
"Mr. Lu, didn't you escape from your marriage before?"
"... That's because I was young and ignorant."
The vests fell off layer by layer, and the truth was revealed step by step. When the shadow of the dark organization is once again shrouded, and when the mystery of his life experience is completely revealed, can Gu Lingshuang truly let go of the past and embrace her own light?
