Fu Sang is a shady character who is formed from resentment. Coincidentally, she time travels in a Mary Sue novel and is bound to a system. The system told her that she had to raise the male protagonist and the villain to become popular so that in the future, they would not turn against each other because of the heroine to complete the task. But Fu sang only had the word “resentment” in her mind. Raising kids = nourishing pure resentment. There is no loss! So Fu Sang sets out on a journey to raise the two kids and discovers that things may not be quite so simple.
