The author has something to say (about KPI)
Some readers asked: What is KPI?
It's the thing where you'll be deducted money if you don't finish your work.
The heroine was a queen in her previous life, serving a scumbag, fighting concubines, and helping him secure the throne—but she was killed.
In this life, she is reborn and quits. Not only did she not do it, she also wanted to get back what she owed her in her previous life, including the principal and interest.
Revenge is her KPI.
The kind that overachieves.
