[A slightly silly, secret-identity-hiding, cocky villainous workhorse, Shen Lili X a sharp-tongued, rich, aloof, transparent supporting-character boss, Yan Shuo]
Shen Lili, a workhorse at the Transmigration Bureau, got scammed by the System. After three years with her brain missing, she came back still a girl in debt. Her fiance drugged her, set her up, and broke off their engagement, planning to give her as a gift to a business rival. At the critical moment, her brain returned, and with it came a tycoon System addicted to shipping couples.
The System said: Spend money on this sharp-tongued man, and you'll get ten times as much back.
So Shen Lili shielded him from booze and bullets by day, and spent money on him for cash back at night. Secretary by day, gaming booster by night, working all year round.
She worked diligently to save up, ready to break off the engagement and rewrite her fate.
Then the System suddenly sounded an alarm: Mission failed.
Wait, during those years when her brain went missing, had she forgotten her main mission as a transmigrator? Wasn't the life of a Transmigration Bureau workhorse still a life?
When she woke up, she was back three years in the past. It turned out that she and her former boss were both insignificant characters in the book. And as the villainess, she was fated to get killed...
Shen Lili: This furious workhorse is starting a revolution. There's no way I'll let this go.
System: I'm not your System anymore. I've become the System of your sharp-tongued former boss.
Yan Shuo: I don't know what she's planning, but she's so cute. I'll secretly give her cheat codes.
Not bad, keep on writing
