Mother Of The Villainess

I didn't need to be hit by the truck to get into the novel nor die from an illness. The only thing I needed to do was die in the stupidest way one could think of. I died from a test of my lover's mother. She was the chairwoman of the very big group. She handed me one hundred million dollars to break up with her son and I accepted it. And that way, I died because it was a test. If I didn't accept the money, she would allow her son to marry me. Her son hired me to be his girlfriend in the first place?? Why am I the one who died just accepting the money?? I'm poor, okay????!!
And now the role reverse when I got into the novel. Of all the characters I could transmigrate into, I became the mother of the villainess, the one who will die alongside her daughter after many schemes and tricks. The villainess aside, but who was the villainess's father? Why am I a single mother?? I didn't know how to raise a baby!!!!
