Teacher Li and Teacher Zhou are a pair of childhood sweethearts, born in the same hospital, Teacher Li is a beautiful boy, and Teacher Zhou is a quirky girl. The home of the two is the distance that can be heard by standing in their yard and calling each other's names, so the two naturally go to the same school, he is in class A upstairs if he studies well, and she is in class B downstairs with average grades, and this distance relationship continues until he graduates from high school.

Upstairs, he will wait for her downstairs to come home from school every day, and she is either punished for not writing her homework for hygiene, or because she is left in class to sleep, and every time he 'rescues', he eventually becomes the target of punishment, and she chatters non-stop on the side, defending herself.

Every day after school, he will go back to her house first, his order is to finish his homework and then play, she is just the opposite, she doesn't want to play with herself, she will not let go of him every time, and he can't refuse every time...... In the end, after dinner, he was called back to his house, she could only bite the pen and smile bitterly, at this time she was annoyed and wanted to be his daughter very much, calling him 'brother, godsister to do homework'.

When he didn't go to school, he followed her to play blindly, go up the trees and go into the water, catch insects and birds, what was fun, and when she grew up, she never admitted this, and he didn't refute it, after all, he wanted to maintain her female image. Every time she made an unintentional mistake, he took the initiative to take responsibility, then she would hide in the corner of her yard 'facing the wall', because he was kneeling on the ground and was beaten by his father with a bamboo stick, at night she would eat a bowl of rice less, and 'smuggle' her own meat into his bowl, and then the next day he continued to be beaten, and she continued to skip meals......

Childhood and adolescence are the happiest and happiest periods for both of them, but time does not stand still.

Mr. Li likes Mr. Zhou, it is the kind of like that boys like girls, and there is no way to explore when it started, but he has never confessed to her, which has become the regret of his life.

After graduating from high school, Mr. Zhou suddenly disappeared! Teacher Li couldn't find it, and during that time he would always sit in the unoccupied yard of her house, thinking about the bits and pieces of the two playing and learning together. As the days passed, Mr. Li went to college in C City, S Province, which was the agreement he made with her when he graduated from high school.

Strange city, strange classmates, in the days when Mr. Zhou was away, Mr. Li became less talkative and lost his smile, if it weren't for his handsome face, he would definitely be excluded from college life by his classmates. In his second year at university, he was dragged by the top bunk to join a club, Jiayuan Society, a cheesy name that doesn't take much effort to know what it does.

Mr. Li began to be pulled in and out of various meeting places by the upper bunk, and saw all kinds of juniors and sisters, his face made outstanding contributions to the development and growth of the club, and also caused a huge burden on his psychology. In the third year, he began to refuse to participate in club activities for various reasons, but after refusing several times, he was forcibly 'escorted' to the scene by the upper bunk.

However, this time he heard Teacher Zhou's name from a school girl who had just returned from teaching in a primary school in a remote area, and she was talking about her volunteer teaching deeds...... After the party, he took the school girl's hand and went out, and the face of the upper bunk was full of interest and evil smile.

After knowing where Teacher Zhou was, he submitted an application to the school, and a few months later, during the summer vacation, he finally met her in his dreams.

Teacher Zhou is very thin and haggard, her hair is tied at will, her clothes and pants are white, and there are a few stains on her chest and cuffs that cannot be washed off. 'Needless to say, the green vegetable furrows, the smooth stone well bars, the tall honey locust trees, and the purple-red mulberries; Needless to say, the cicadas are singing in the leaves, the fat wasps are lying on the cauliflower, and the son of heaven suddenly rushes from the grass to the clouds...... 'Teacher Li returned to his primary school in a trance, he also studied in this way, but he never heard her read, because he was not in a class, and she was even more reluctant to read to him after school.

Listening to her voice at this time, his eyes were moist in shock! Stand outside the window and listen to the lecture before going to report.

For Teacher Li who suddenly appeared, Teacher Zhou didn't show too much enthusiasm, but the tone and order of her speech were still the same as before, and he didn't care about it when he was full of joy. A few days later, he learned from another teacher in the village that her boyfriend had died in a car accident some time ago, and the car had fallen off a cliff and his body was gone......

This 'answer' left him at a loss, he liked her, he liked someone else, and that other person is now dead!! For the first time, he felt the deep meaning of the idiom 'thunderbolt on a sunny day'.

In the end, Ms. Li stayed, teaching math and physical education, taking care of two classes of children, and sharing a lot of her work. lived next door to her, took over the cooking, and looked at her thin body and he knew that she hadn't eaten well to take care of herself. She would obediently go to his dormitory for dinner, help wash the dishes, and then the two of them would go to the office together to prepare for class. She has changed her words, restrained her flamboyance and carefreeness, matured like an alien from afar, and the sadness in her eyes is often carried by him, he sees it all in his eyes, his heart is aching, but he can't do anything except take care of her in life and work.

The days passed like this, everyone thought that Mr. Zhou had come out of the pain and accepted Mr. Li's pursuit together, and even he occasionally had such an illusion, but she still kept a good friend distance from him, not far away. She didn't take the initiative to tell him about the years she had been gone, and she didn't say a word about 'that person', he still learned about them from a third party, and he wouldn't take the initiative to ask her...... If she were just a good friend of his own, he would ask.

Teacher Li actually knew that Teacher Zhou didn't like him, he and she had been together from the age of one to eighteen, and he knew her too well! She didn't say it was because of his relationship with her childhood sweetheart, and when the window paper was pierced, the cold wind would blow in, so she wouldn't say it.

Mr. Li's teaching time was about to expire and he was going back to school, but in the end he couldn't sit still.

He asked her to go to the big ginkgo tree at the foot of the mountain behind the school, she knew what he wanted to say, so she didn't let him speak, and talked about her encounter and love with 'that other person', very slowly and in detail, her expression and tone were full of sadness. "I'm here because of him, and I'm here for him."

"I ......" "......" the cold and silent air, at this time the withered yellow ginkgo leaves fell on his arm, picked up the leaves and looked at it in a daze, his heart felt very dull, breathing was a little difficult, and he exhaled for a long time, and suddenly the energy in his heart disappeared without a trace.

"Take care of yourself! Don't lose weight anymore, I don't think kids want a 'kid teacher'. She nodded.

Teacher Zhou went back to school first, and Teacher Li squatted under the ginkgo tree for a long time and blew the cold wind, crying like a child, and the tears on his face were dry and wet, wet and dry...... After that day she never ate his dinner again.

The next day, Mr. Li returned to the university, and after finishing his studies a year later, he sent a letter to his family and left the school with his bag on his back, and no one knows where he went and whether he was doing well. Occasionally, his parents would receive letters from him announcing his safety and extra numbers on his bank account.

Teacher Li, who lived a wandering life, did not go to Mr. Zhou again, but just used his camera to take pictures of every person, thing, and thing similar to her, and he never thought about the next relationship, only knowing that she had entered his life since he was born, and now it is impossible to separate.

Later, Mr. Zhou saw a photograph in the newspaper called "Following", in which the boys in the crowd looked at the girls, no matter how complicated the world was, the boys only had girls in their eyes...... Teacher Zhou silently wiped away the tears from the corners of his eyes, smoothed and folded the newspaper and stored it, and picked up the textbooks and lesson plans to teach the children.

In the end, Mr. Zhou will live forever in Mr. Li's memories.

"Cards!"

"Finished."

The crew began to get busy, and two inconspicuous women were chatting secretly.

"You know what! The heroes and heroines of this play are in love, and their love path is as bumpy as this movie! ”
