Summer Hidden in Soda

University campus, hosting two pairs of CPs: CP1: (Childhood sweetheart) When Gu Nianzhi was eighteen years old, she was admitted to Peking University, and she could finally legitimately follow the person who grew up with her. Jiang Yumo is the pride of heaven in the eyes of everyone, and he is also the "brother Yumo" she has called since she was a child. He remembered all her hobbies and took care of every trouble for her, but he still refused to admit that his care had already exceeded the boundaries of brother and sister. Gu Nianzhi asked him with red eyes: Do you want to be my brother forever? CP2: (Second male on top) Lu Zhixi only studied for two years as an undergraduate, then went to Columbia University's exchange program. After studying for graduate school, he returned to Peking University. Before she left, everyone in the business school thought she and Chi Yanzhou were a good match. The window paper was thin but not torn, and she was gone. She came back two years later and joined the same instructor's research group. There is one more person beside Chi Yanzhou... Some people learn to be brave before they miss it, and some people choose to say goodbye after meeting again. Youth is never just about perfection. Some people finally fall in love with each other side by side, while others admit that they have loved each other but never look back.
