In the days when green trains were still very crowded...
English teacher Mu Xiao embarks on his own "wandering" journey, and senior Qin Yunfeng steps into the car where he experiences life.
She has an ordinary appearance and old-fashioned thinking, and is depressed by the blow of a broken love; he is handsome, sunny and cheerful, and his disadvantaged upbringing in a wealthy family has not changed his sincerity and kindness.
She didn't want to talk to anyone and just wanted to be sad in her own memories; he was very nosy and wanted to help the silly girl in front of him regain her confidence and live a strong life.
She thought she was saying goodbye after a chance encounter, but she actually meant never seeing him again. Little do they know that every time they say "goodbye", it heralds the next goodbye.
They promised to be friends, promised to be confidants, but when she cried herself to sleep and woke up early in the morning, there were words of concern on the other end of the phone, and she was a little unsure of her own heart. When he could no longer listen calmly to her talking about the past and her going on a blind date with her family, he firmly believed that this was no longer friendship.
Fifty years later, a pair of white-haired old men stood on the top of a mountain watching the sunrise. The old man slowly took out a small iron box from his arms, with a piece of light goose feather lying inside. Then the old woman remembered one afternoon many years ago, a girl with a ponytail chased a group of geese in the sunshine, and finally successfully plucked a piece of goose feather from the buttocks of one of them and sent it to a friend far away. The old man asked: What did you want to say when you sent it to me? The old woman shook her head, "I don't know, or maybe she remembered an agreement: we still have a direct train that we haven't taken yet?" The old man quickly put away the iron box and took his wife's hand, "Let's go, take the train."
Concept: Sunshine always comes after the wind and rain. It can be encountered but cannot be sought.
