Genie Lo lives in a modest town and wants to go to a prestigious university. She plays on the volleyball team, crams her textbooks, and tries to figure out what she needs to do to get accepted into Harvard University. But when demons from Chinese folklore appear in her hometown, her priorities change dramatically. Enter Quentin Sun, a mysterious new kid in class who appoints himself as Genie's assistant in fighting demons. Genie only knows Quentin as a cute exchange student who speaks good English. In another reality, he is the Monkey King of myth, a reincarnated version of himself, with a bushy tail and a love for peaches. And suddenly exams become the least of Genie's problems. The fates of her friends, family and everyone around her depend on her inner strength, which, according to Quentin, is powerful enough to defeat Heaven's Gate itself. But while Genie spends time uncovering the secret of her true nature, the lives of her loved ones hang in the balance.
