When Tang Xiaowu, a struggling high school senior, jolts awake from a dream of the underworld, he finds a peony tattoo on his waist that burns hot. Even crazier, the problem-solving tips Yang Ruoxi taught him in the dream and the competition topics Zhao Qian marked out seem to drop straight into reality.
He used to be the target of Lin Weiwei's rumors that he “got by on connections.” Now he crushes his mock exams with methods learned in his dreams. The secrets won't stay hidden in his rented apartment: the key to a luxury home Zhao Qian gives him opens a villa identical to the one in his dream. Even the materials Chen Shu gives him at the library always contain notes that seem to predict danger, as if she already knows the villain Zhou Kai plans to use him as leverage to bring down Zhao Qian.
As he turns his life around with gifts from his dreams, his heart remains torn. His concern for Yang Ruoxi in the dream hasn't faded, while his feelings for Zhao Qian in real life keep growing. And he can't understand why the strange connection he shared with Chen Shu in the dream makes the tattoo's power grow stronger and stronger.
Only when Zhou Kai's plot entangles itself with the tattoo's secret does Tang Xiaowu realize that this dream spanning two worlds was never an accident. The bonds hidden in its patterns demand that he risk his life in the real world to protect them.
