This novel is based on a true story, but it also phantoms the future development, adding imaginary plots to the only real experience, which plays a finishing touch. It tells the story of a girl's loyal love for her first love, who is considered a childhood sweetheart. When she fell in love with the boy but was betrayed, she still waited patiently with her original intention. Finally, her waiting was favored by God, and the boy returned to her. By chance, she found out how much her best friend loved this boy. After hearing what her best friend had said for the first time in years, she felt it, and she decided to give up on this relationship and bring them together. After she painfully broke up with the boy, she encouraged her best friends to fight for their own feelings, but the result was unsatisfactory. Her best friend suffered from a boy and she blamed herself for leaving. Later, the boy used various methods to find her, and with the persuasion of her friends, she returned to the place where she originally lived. But after attending her friend's wedding, the boy proposed to her again and again. The last time she agreed, and after that day, she left forever.
