Marigolds, also known as "spring every day", if they bloom before seven o'clock in the morning, it means that the day will be sunny, otherwise it will be a rainy day. Before the flowers bloom, nothing is decided. The weather is like this, people are like this, and time and space are like this. A notebook that can travel through time and space in both directions, a mysterious "return" photo studio, is the encounter between modern female teacher Bai Zhi and Republic of China pilot Gu Yu accidental or destined? What secret does the photo studio owner hide? Please wake me up before leaving, don't let me be trapped alone in this endless unknown.
Purpose: Love and feelings of family and country
