Su Nian's mission is to enter the world of the novel and repair the emotional loopholes of the male protagonist.
In the apocalypse, she makes the ice fields full of flowers. Deep in the palace, she taught the suspicious emperor to trust him. Ten worlds, ten lives, she thought she was just completing the task.
Until the last world, she discovered that all the male protagonists were the same person - and that poisonous system "timing" had been waiting for her to discover the truth.
"Have you always been here?"
"I've always been there. From the first world on, I've been waiting for you to recognize me."
