An Xiaoqi was admitted to Shanghai Donghua University of Science and Technology in 2012, bidding farewell to her hometown in a small county. In Shanghai, this ordinary and slightly chubby girl met two people who reshaped her life. One was the dazzling senior Jiao Zi'ao, the president of the student union, and the other was the quiet academic master Yu Shiwen whom she met in the study room. University is a place responsible for making dreams, whether it is a dream that you are addicted to or a dream that finally comes true. When four years have passed by and everything has settled, all the joy or grievances that were once felt are just a murmur kept in the heart of this city in the vast sea of people.
