Zhou Shenai is an older young man and a freelancer. He is free between the city and the countryside, and at the same time, between bondage and freedom. He is floating in the air with his thoughts, stable and uneasy, fulfilled and depressed. Chu Qingran, a middle-level corporate man who worked as a topic writer in a small town, stepped into the spotlight and worked hard all the way. He was barely a successful person. However, life brought him not only high spirits, but also uneasiness and anxiety. The two fell in love for the first time, but each chose a different path. Now that they meet again, old hurts and feelings come flooding back. At that time, both parties understand that time cannot take away the regretful past. The life that has to move forward burns out the fire in the heart and achieves materiality and emptiness along the way. They stood on the plane of life and saw that their own lives were vast, but they saw each other standing at the exit of the fog. They each know the answer to the other's life, each unexpected answer.
