Top hacker Sang Jiu wakes up and time-travels into a cheesy webnovel, becoming a crazy illegitimate daughter in a psychiatric hospital. To slack off peacefully, she acts crazy and calls herself the Emperor, acknowledges Chu Wenye—who is enduring stoically and disguising himself as a patient—as her great-nephew, and also gets to know Huo Yu, who was wrongfully admitted. While pretending to be foolish to figure out everyone's cards, Sang secretly manipulates the network, investigates her own amnesia and the original character's past, while Chu Wenye also hides his motives to search for the mysterious hacker Nine, and the two test each other.
