In a nutshell: the daily bickering between a sharp-tongued heroine lying low and a frustrated System-bound male lead.
Jiang Hui died alongside Meng Beichen. When she opened her eyes again, she had been reborn three years in the past.
Even more absurdly, Meng Beichen, who had fallen with her, had become a System and taken up residence in her mind.
A flood of unfamiliar memories made Jiang Hui finally realize the truth: she was the wicked supporting female character in a novel.
In the original story, she repeatedly framed and hurt the heroine, Ning Qinghe, until everyone turned against her. In the end, Meng Beichen personally sent her to prison, and she met a miserable fate.
After facing reality, Jiang Hui struck a deal with Meng Beichen, trapped inside her consciousness.
She would complete his missions and help him come back to life. In return, he would help her take over her father's company.
But beneath the bargain, each of them had their own agenda.
Would Jiang Hui, who never let a slight go unanswered, really obediently act as his tool and complete his missions?
And why would Meng Beichen, who had finally found a chance to come back to life, suddenly have his soul ripped away in the middle of an important meeting?
The two enemies, who would both love nothing more than to see the other disappear forever, found their feelings quietly shifting as they sparred.
"Jiang Hui, why does my heart pound whenever I see you now?"
"Oh, maybe you're about to die. Want me to buy you a coffin?"
"Can I be buried with you?"
Jiang Hui sneered. "You hogged my brain while you were alive, and now you want to steal my grave too? Why not just cremate yourself and scatter your ashes?"
