"Teacher Ye, Teacher Ye!" Amid the noise, Ye Lengsong was pushed awake by the people around him. 

"Lengsong, it's your turn to go on stage." Ye Lengsong stood up passively and walked towards the brightly lit stage guided by the staff. 

Only when I got closer did I see the banner on the stage: Beijing Film Academy 2002 New Year's Eve Gala. 

"Fuck, where is this? Am I not a teacher in the mountain village? Why am I here?" 

Ye Lengsong remembered that he was a volunteer teacher in Northwest China and was eventually buried in a mudslide caused by a landslide. 

For a moment, he suddenly felt a splitting headache, and all the memories of his past life and the memories that he was not familiar with flooded into his mind. 

Before he could think about it, a little girl who looked like a student had walked to the back of the stage and handed the microphone to Ye Lengsong, saying, "Teacher Ye, keep going." 

Such a familiar girl, Ye Lengsong couldn't remember who she was for a moment, then a light flashed in his mind and he seemed to remember something, "You are... Lin E?" 

Ye Lengsong felt something was wrong after he finished speaking. Lin E was a character in a TV series he had watched before, "The Road of Life is Full of Longevity". 

"My name is Yang Xue. Teacher Ye taught me before. How could you forget it? Come on, the host is running out of words." 

The new memories in Ye Lengsong's mind became clearer and clearer. He is now a teacher at the Beijing Film Academy and one of the youngest teachers there. He is 22 years old this year and has been teaching at the academy since graduation. Now is the teachers-student party at the Beijing Film Academy to celebrate the New Year's Eve of 2002. 

Although Ye Lengsong originally studied acting and took elective courses in directing, he was born with a good voice and was young, so he was recommended by his teachers to sing a song. 

He originally chose an old song that was suitable for the occasion, "You, My Deskmate". The accompaniment tape was ready, waiting for him to go on stage and sing. 

Ye Lengsong was still in a dream at this time. As soon as he walked onto the stage and adjusted to the stage lights, the host smiled and said according to the pre-rehearsal content: "What program are you going to bring to everyone today, Teacher Ye?" 

Ye Lengsong's years of experience as an elementary school teacher helped him calm down quickly. The difference in his original personality made him somewhat repulsed by the song "You, My Deskmate". 

After just a moment of hesitation, Ye Lengsong picked up the microphone and said, "Today I will sing a song for you, the name of which is "You in the Past"." 

The host broke out in a cold sweat, as this was inconsistent with the previous preparations. Although their party was a small one, as a top-notch film academy in the country, such parties would be recorded by several cameras. If the results were good, it might even be broadcast on local TV stations. 

Now the accompaniment of "You, My Deskmate" is ready, and it's just waiting to start playing. However, Teacher Ye suddenly changed the song without telling the program team in advance. 

The host still had some manners. He thought about it and immediately replied, "Oh? I've never heard of the song "You Once Upon a Time". Are you going to sing it a cappella or play it?" 

"'You Once' hasn't been created yet?" Ye Lengsong thought to himself. 

"Yes, Xu Wei only started writing Once Upon a Time in 2004." 

Faced with the host's question, Ye Lengsong had no choice but to bite the bullet and say, "Let's play the guitar and sing. Please give me a guitar and a high chair." 

These things were all prepared by the program team. Soon the staff brought a round-horn guitar and moved a high chair to the center of the stage. 

Ye Lengsong, who was forced to do this, had not yet adapted to his new identity when he had his first solo show. 

After fine-tuning the tone of the guitar strings, Ye Lengsong didn't care about anything else. He finished the song first and then thought about how he got here after he got off the stage. 

He cleared his throat, plucked the strings, and began to play and sing by himself. 

"I once dreamed of traveling the world with a sword and seeing the prosperity of the world. The heart of a young man is always a little frivolous. Now you are at home everywhere. The girl who once made you feel distressed has now disappeared quietly. Love always makes you long for it and feel troubled. It once left you covered in scars..." 

Ye Lengsong, who is already very handsome, wore a Zhongshan suit. It was originally designed to suit the occasion for the movie "You, My Deskmate", but now it doesn't look out of place when he uses it to sing this song. 

When Ye Lengsong sang the second verse "The girl who once made you feel distressed has now disappeared without a trace...", the students in the audience could no longer sit still. They all stood up, and some even stood on their chairs, causing dissatisfaction among the students behind them. 

Xu Wei's song "You in the Past" can resonate more among contemporary students than Gao Xiaosong's "You, My Deskmate". 

If "You, My Deskmate" represents the purity and innocence of middle school days, then "Once Upon a Time" represents the ideals and reality of college and graduation days. 

"Let's drink this glass of wine. A good man's heart is like the sea. He has experienced all kinds of life and the ups and downs of the world. This smile is warm and innocent." 

After singing the last sentence, Ye Lengsong stood up without any hesitation, bowed to the audience while holding his guitar, and turned to leave. 

I don't know who took the lead. At first, there were only a few people. Before Ye Lengsong walked off the stage, the students shouted in unison: "Teacher Ye, I love you!" 

Ye Lengsong, who had already walked off the stage, did not notice that one of them was his future goddess, Liu Yifei, a freshman from the class of 2002. 

… 

Ye Lengsong realized that he had traveled through time. After confirming that it was not a dream, he looked at the campus full of slogans and posters celebrating the New Year's Day 2002 and could only accept this fact. 

"Congratulations to the host for completing the much-anticipated achievement. System rewards: Charm value increased by 10%, opposite sex attraction value increased by 10%." 

PS: The higher the charm value, the more people will like you and have a good impression of you. The higher the opposite sex attraction value, the more attractive the host will be to the female he likes, and the more willing she will be to commit herself to you. 

The voice in his head gave Ye Lengsong a shock. After confirming again and again that there was no one around, he believed that the voice was really speaking to him. 

Time travel can happen, and with the addition of a system, Ye Lengsong is no longer surprised. There are too many complicated memories mixed together in his mind, making it difficult for him to distinguish which are from his past life and which are from this life. He ignores the students shouting in unison in front of the stage, searches the memories in his mind, follows the backstage path, and jogs back to his teacher's dormitory.
