In the late summer of 2019, on the first day of school at Lixiang No. 1 Middle School, the life trajectories of Han Zhiwan and Feng Linkai quietly intersected. One is a girl with a gentle and tolerant personality who rushes to school in a hurry, and the other is a cool, clean and thoughtful young man. A bunch of lost keys becomes the starting point of their youth story.
In the three years of high school, a small group of five people have been together all the way: An Congman, who is casual and frank, and Fang Yiwen, who is calm and reliable. Together with Han Zhiwan and Feng Linkai, under the scorching sun of military training, under the pressure of monthly exams, and in the shouts of sports games, they have gone from strangers to tacit understanding, and from youthfulness to maturity. Feng Linkai's silent protection, Han Zhiwan's gentleness and transparency, and the feelings that quietly sprouted in the day after day became the most touching secret in youth.
After graduation, the five people went to different life tracks: Han Zhiwan became a broadcaster and host, Fenglinkai soared thousands of meters high and joined the police force at will, An Congman devoted himself to medicine, and Fang Yiwen traveled far and wide. An unexpected misunderstanding caused Han Zhiwan and Feng Linkai to miss each other for many years. It was not until a life-and-death test at an altitude of 10,000 meters that the two finally confessed their feelings and untied their dust-laden worries.
In order to make up for their youthful regrets, they joined hands on the stage of a love variety show, relived their heartbeat in front of the camera, and disclosed their two-way secret love for many years. Old friends gathered to help, parents approved and blessed, from engagement to getting the certificate, from living together to the wedding, the little thoughts that were once hidden under the desk finally turned into a firm commitment to stay together for the rest of their lives.
This is a period of youth and love that spans more than ten years. It witnesses the growth and transformation of young boys and girls, and also explains the perseverance of friendship and the persistence of love.
