Zhao Yi is a marginalized girl with mediocre grades and poor sociability on campus. She accidentally meets a male protagonist who is a popular figure on campus and is younger than her, and a sister-brother relationship begins. However, their love was not always smooth sailing. Because the love rival was jealous that Zhao Yi could be with the male protagonist, he constantly created misunderstandings and tried to destroy the relationship between the two. At the same time, as the college entrance examination approaches, Zhao Yi faces a dilemma between love and studies. Should he focus on his studies and work hard for the future, or devote himself wholeheartedly to love. The differences in family background that the male protagonist has always hidden are exposed at a critical moment, triggering an emotional crisis for the two. In the emotional triangle, Zhao Yi faces the male protagonist and the suitor, and is confused about how to make a choice. Campus public opinion is not optimistic about their sibling relationship, which also puts huge pressure on the two. However, despite many difficulties, they encouraged each other, grew up together, and worked hard to balance their studies and relationships. They finally broke through the difficulties and moved from campus to marriage.
