The story has to start with a notebook...
Bai Simian picked up the notebook of top student Li Yujue. What was hidden in it was not the ideas for solving the problem, but his gambling father, his angry mother, his innocent sister, and her broken self. It turns out that the setting that is only given to the heroine of the novel actually exists in a person.
But when she approached cautiously, trying to offer some warmth, she learned that Li Yujue was originally a young lady born with a silver spoon in her mouth. A conspiracy caused her to fall into the abyss, and the person who pushed her was Bai Simian's relative.
