Oh, My Scumbag Ex-Husband Is Also Reborn?

Just after giving birth, the vicious mother-in-law asked me to wash clothes, cook and serve the whole family. She also wanted to sell my son to a human trafficker to pay off the gambling debts of my scumbag husband! What a spring and autumn dream! My scumbag ex-husband is also reborn? That's just right, it's time to pay back what I owed me in my previous life. It is impossible to forgive. Are you saying that I am evil and cruel and inhumane? Haha, how can we talk about humanity when dealing with scum?
