They fell in love at first sight. One is a ballroom dance coach, and the other is a talented musician from the Normal University. They are in love with each other, they are in love with each other, and they love each other deeply. They had the beginning of falling in love at first sight, and they would have had a happy ending. But in order to repay her first music teacher, she insisted on returning to teach in a poor mountainous area. She asked him to wait for her for three years. But he disagreed. He was angry at her "selfishness and willfulness" in love, and he let her go in anger! Unexpectedly, in just six months, the music class that she dreamed of changing the spiritual world of students was rejected and attacked. "Music has no effect on our college entrance examination. We don't want to take music classes!" Only one girl stood up to argue for her. However, this girl was abused by the youth in society and became insane! She finally realized that her decision was wrong and she shouldn't come back to this place at all. So, she walked into the mountain pond in front of Teacher Lian's cemetery... At this time, he was looking for her with her farewell poem and a bag on his back... After all, are they still destined to be together...
