They both almost simultaneously developed a crush on the handsome intern teacher Luo Jia (played by Ren Quan). Under Annie's active pursuit, she eventually became a couple with Teacher Luo. After graduation, Wenxin, with no background, became the most popular hairstylist at a salon, while Annie, after living with Teacher Luo in the U.S. for two months, returned to China without receiving her boyfriend's wedding ring, as Teacher Luo intended to propose to Wenxin.
