18-Year-old Yang Xueqing was admitted to the top Jinhai University in the country. She wanted to spend four years in an ordinary life, but unexpectedly reunited with Gu Yanting, the "cold-faced academic" who she had a crush on in high school. Gu Yanting was still the cold and abstinent school boy with unparalleled grades, but he showed a completely different side to Yang Xueqing - he would carefully remember all her habits, appear when she needed her most, and calmly remove all obstacles for her.
Their story begins with an unexpected "living together", heats up every time they look at each other in the library, and leaves sweet marks in every corner of the campus. But when misunderstandings, love rivals, family pressure and future choices ensue, can this relationship be as eternal as the stars?
