The story of "Youth is Like a Dream" tells the story of Ling Yun, a seventeen-year-old boy who has no handsome appearance, extraordinary talent, and even a little low self-esteem, but he has a crush on Wen Min, the school beauty recognized by the whole school. In junior high school, Ling Yun and Wen Min were in the same class. Ling Yun, who was sitting in the back row, began to develop the habit of peeking at Wen Min who was sitting in the front row, and began to draw her back and write her name in the textbook. However, Xia Yu, who had just transferred to another school, unexpectedly sat next to Wen Min, and mistakenly thought that Ling Yun was peeking at her. Because of this habit, Xia Yu, who was cheerful and bold, also began to pay attention to Ling Yun. It was not until one day when she asked Ling Yun that she learned the truth, but Xia Yu had slowly fallen in love with Ling Yun. Because there were so many people who had a crush on Wen Min, and Wen Min wanted to study and didn't have a boyfriend, there were always a few people who started to harass Wen Min. The introverted Ling Yun couldn't help but start to protect the object of his crush. However, due to his lack of strength, he was injured several times in a row. At an age when youth was rebellious and love first emerged, Ling Yun had his own emotional world. Between loving and being loved, his heart began to change. The loneliness that no one understood under the youthful rebellion pushed Ling Yun towards Xia Yu.
