Because of her long commute from home to work, Wang Cuihua spends her time reading web novels. She reads so many of them that after two years, she is able to guess where the plot is going to lead just by reading the first lines.
 
One day, she starts a new work where the heroine transmigrates in a novel but it quickly bores her. However, while trying to leave the page, she finds herself sucked into her cell phone. She then wakes up in the novel as the concubine Yu Wanyin, one of the antagonists of the story.
