Youth is fleeting, and grass is easy to wither. Time is like a creature with divine power, always repeating the same things, it will make trees wither, it will change people's hearts, it will make dreams come true, it will make people meet girls who want to protect their lives but have no ability to protect them in the best youth...

In 3015, he entered the ideal high school alone, in his war song. I met a girl he liked and wanted to protect for the rest of his life. The girl is beautiful, kind, gentle, considerate, and lovely, but her eyes are often full of melancholy. The boy sat in the last row and often looked at her secretly, and she felt the boy's emotions. The two always maintain a tacit understanding. In the morning, the boy would pass by the girl's seat and smile at her; During recess, the girl would go to the last row to get hot water; At the end of the evening, the boy would be at the intersection, watching the girl come home, the light at the door went out, he knew that the girl was home safely, so he left. And so it goes, day after day...

A year has passed, finally, in the second year of high school, the boy confessed to her, she was full of joy, and her face was filled with a glimmer of happiness, but she couldn't agree, she had her own dreams, very persistent goals, and the university she wanted to go to, and she knew clearly in her heart that the two of them were impossible! No matter how hard the boy tried, he couldn't keep up with her at all, but she didn't know that the boy would make him happy just by seeing her laugh, so she could only say: "Let's make an agreement, in a year after the college entrance examination, if you can go to the same school as me, I will promise you!" She knew: it couldn't be! The girl wants to make the boy better, the boy believes it, and makes himself better like a different person, and the buddies around him feel that he is stimulated. Only he himself knows that the future ... You can decide for yourself. Studying, reviewing, watching the girl smile, he repeated it like a machine, and he found that he had really changed. Looking at the countdown 300, 220, 149, 100, 20, 10, 4, and 4 days of college entrance examination, on June 3, 3018, he took a graduation photo, and the girl was so beautiful that day, he stepped forward: "Tang Xue, do you remember our agreement a year ago?" If I could, we'd be together. The girl thought that this was no longer possible, that the boy had become better, that he had surpassed himself, and that the boy who had once made his heart flutter might not come back. She smiled and said: "Qingyuan, of course, we said that no one can go back on the one-year contract." ”

The two days passed quickly, and the weather was also very comfortable, except for the thoughts between the two, and the rain as always, washing away the hard work of the year for all college entrance examination candidates. During the holidays, he went to work, and wanted to go out with the girl during the first vacation of the university, see the scenery outside the college entrance examination, and ask the girl what school she wanted to go to in his spare time, and he knew. On the day the results came out, the network was paralyzed, and he didn't find out until the second half of the night, and he couldn't wait to call the girl, but all he heard was the girl's cry. He was in a hurry, the girl hung up the phone, knowing very well in her heart that this agreement could not be realized, she played abnormally and had no chance. But she hoped that the boy would follow his true heart, and called the boy with tears in her eyes: "I am higher than you, haha!" This time I listen to you, where you want to go, I will accompany you. ”

On the day of admission, everything was settled, and the girl left the city without saying goodbye, leaving only a letter:

"Qingyuan, you have become good enough, I can't keep up with you, if there is fate, maybe one day, we will meet again! Go chase your own dreams!

----I used to like your Tang Xue"

The boy knew that all this could not be changed, and he stood at the intersection as always, looking at the direction of the girl's home, but there was no more girl, and he would never hear again: "This is our secret place, if you can't find me, come here, I'll wait for you!" And that light will never go out again.

In the blink of an eye, in September, he wanted to become a teacher on the three-foot podium, went to the normal university he wanted to go to, met new classmates, new roommates, and counselor teachers, and the memory of that summer gradually faded. Everyone said that his eyes were special and often full of melancholy. But no one knew that that the separation took away all his memories of Tang Xue, and even he didn't know that his future had been changed, and he only felt that there was some kind of power calling him to come here. And he started a new life...
