In Class 7, Grade 2 Science, City No. 1 Middle School, Lu Chenzhou, a silent and stern academic god, and Jiang Nuan, a quiet and hard-working person, became roommates. The lively and cheerful liberal arts student Su Yong and the sunny and loyal Han Chaoyang formed a solid friendship team.
During the three years of high school, they faced together: the choice of liberal arts and science subjects, the unknown English shortcomings of academic god Lu Chenzhou, the misunderstanding of "hero" caused by Su Yong's accidental fall into the water, the pressure of competitions and art exams, and the quietly growing but indescribable feelings. Lu Chenzhou protected Jiang Nuan in his silent way, while Han Chaoyang had been hiding his concern for Su Yue with playfulness.
After the college entrance examination, they went their separate ways: Lu Chenzhou entered the military academy, Jiang Nuan entered the top medical school, Han Chaoyang followed his mother's footsteps and went to the Military Medical University, and Su Yong joined the art world. The distance between them has not widened. During the four years of college, they have worked hard and grown up in their respective fields - Lu Chenzhou has become a calm military officer, Jiang Nuan has overcome obstacles on the road of medicine, and Han Chaoyang and Su Yong have gradually seen each other's feelings clearly through constant bickering and concern. They share their lives through the small mobile phone screen, support each other, and develop deeper emotions during each holiday reunion.
This is a journey of growth that spans many years. It tells the story of how a group of four went from being young high school students, through the tests of studies, dreams and emotions, and finally fulfilled the promise of youth and gained the fulfillment of career and love. Lu Chenzhou and Jiang Nuan went from being silent at the same table to working together for a lifetime, and Han Chaoyang and Su Yong went from being happy enemies to recognizing each other, and together they composed a warm and touching youth drama.
