Lin You, the "ghost king" of the Department of Journalism, has been secretly in love with Jiang Fan, the aloof top student in the Department of Computer Science, for many years. However, because of their status as "brothers" who they grew up with, they can only hide their feelings in jokes. Jiang Wan is a typical straight man. He interprets Lin You's every show of affection as "brotherly love" based on his strength. He not only accepts her concern calmly, but also always pulls her to hack, fix computers, and even ask her to help ward off romantic relationships. While Lin You was complaining crazily in her heart, she was silently cooperating with his "brother's script", until her secret love diary was accidentally discovered by Jiang Wan, and the "brotherly love" that had lasted for many years finally came to a turning point. Jiang Wan began to face up to his special concern for Lin You, and transformed from a "good brother" to a "wife-protecting maniac". With the help of his roommates, the two crossed the line of "brothers" and went from childhood sweethearts to a sweet love that goes both ways. They wrote a relaxed, humorous and healing youth story at Nancheng University.
