The story of two young ladies from campus to campus (both became teachers when they grew up). One of them studied abroad in high school. The story begins after graduating from college, with many memories interspersed throughout. In short, it is the journey of the idealistic and gentle Miss Gu pursuing the smart, cute but sad Miss Zhou for more than ten years. Feelings are ups and downs, unknown. Ps. Some of the characters' names are tributes to characters in the author's favorite works and real-life characters.
