Yi Nian traveled back to Xiangjiang 20 years ago and met the popular singer Lin Chu. The two went from misunderstanding to acquaintance to falling in love. However, Yi Nian would eventually return to her own time, and she did not dare to make too many promises. Lin Chu did not back down, after Yi Nian was discovered by reporters. He bravely admitted his feelings to reporters and protected Yi Nian well. In the end, Yi Nian returned to 2017. Before leaving, Lin Chu said that he would wait for her as always, but Yi Nian didn't say the words "I love you" until the last second.
In 2017, Yi Nian frantically searched for news about Lin Chu, only to discover that he had already retired from the scene before 15 and no longer appeared in the public eye. She returned to Xiangjiang, the hotel was still there, and she went to every place they had ever visited. It wasn't until one day when she saw the information about Lin Chu's "20 Love You" concert that she remembered what Lin Chu had said after knowing her secret. Even if she went back, he would wait for her and hold a concert on Christmas 20 years later, waiting for her to come.
Concept: Love will not change with time, there is only love or not.
