It tells the fifteen-year growth story of transfer student Xu Linlang and the talented senior high school student. Transfer student Xu Linlang took a leave of absence due to illness and transferred to the class of Wen Ping, the talented sister of the senior high school student, and became Wen Ping's deskmate. The dramatic encounter between the two opened the curtain of the Youth Theater. The two childhood sweethearts who also loved foreign languages fell in love and agreed to be admitted to the same university. After graduation, they became diplomats together, but they missed it due to a twist of fate. A novel that is a bit sadistic, a bit sweet, and a bit sad.
