The Glamorous Doctor Divorces Her Husband

I am a modern-day physician, that transmigrated, and became a concubine.
Abandoned by my lord, other concubines are constantly trying to find fault in me.
Originally I did not have much interest in trashy men, and lived fairly peacefully.
But sisters, heed my warning and be kind.
After all, I used to work with a knife, and I've drawn blood, unlike you, who can't even take a small scare.
