An empty package with the clue of "sos" becomes the signal for help from the school goddess Hatsune Yinyin, who is missing. Hatsune Yinyin loses her memory after being attacked and drifts to a vocational school in the suburbs. On the other hand, Xia Er, who is being chased for debt, decides to go out to find an opportunity to make money, but is mistaken for Hatsune Yinyin and enters the prestigious Ivy League College to start elite learning and life. The similar appearance and the weird behavior of the people around her make Xia Er suspicious. Where did the real Hatsune Yinyin go? Xia Er, who decides to stay and find the truth, meets Xu Konglin (played by Zeng Shunxi), a cool and hot academic tyrant, and Li Bai (played by Wang Bowen), a cheerful and warm-hearted sunny boy, at school. More and more clues surface, and a campus story about youth, love, dreams and adventure is about to unfold.
