Zhou Jiamu, who is the first in grade, and Ji Anming, who is second in age, were assigned to the same class in their sophomore year of high school. They became roommates for no apparent reason. At first they were tit-for-tat and fought to the death, but over time they fell in love. After they got together, they loved and protected each other, but life is always ever-changing. Ji Anming became acquainted with the situation due to his childhood experience. He suffered from depression, and he was afraid that Zhou Jiamu would hate him and not want him. He left alone, but they did not let go of each other. Later, Ji Anming became a lawyer and Zhou Jiamu became a pilot. The two people who would never see each other again met the person they wanted to see the most because of fate, and they both became the most important person to each other.
