Saying goodbye to the love that lasted for three years, Mu Yao decided to use travel to heal the pain of three years for one day. Carrying a big bag, she stood in the huge train station waiting hall, waiting for the late-night train like the tired crowd. At this time, the seats were full. In order to pass the time, she paced back and forth in the waiting hall, looking at the students around her who were about the same age as her. They were in groups, talking and laughing. She couldn't help but see the loving couples, and she felt a burst of sadness in her heart. Although they are similar in age, they have never met before. When I think about spending the next fourteen days with them day and night, I instantly feel so lonely.
