Their fates are so entangled.
Fifteen-year-old Su Ange traveled to Lhasa alone and met the gentle and elegant man, Luo Jinfan, on the train. They traveled with it for a week. Su Ange fell deeply in love with this man who was thirteen years older than herself.
When they parted, they made a three-year appointment. Three years later, whether her feelings for him remained the same.
Su Ange returned to Chongqing and Luo Jinfan returned to Hangzhou.
Sixteen-year-old Su Ange rescued the handsome boy from a group of hooligans. The boy's name was Mucheng, and Mucheng clung to Su Ange like brown candy. He was three years younger than Su Ange. That day, Su Ange left her father's wedding, but accepted Mucheng's sudden confession. Su Ange rejected the enchanting Mucheng without hesitation. Mucheng left Chongqing and went to study in England. Mucheng told Su Ange that in five years, he would follow her every step.
