Weather forecaster Xu Jinzhao reunited with his childhood friend Lin Xue who had become a mountain rescue team member at the lowest point in his life. The two embarked on a journey together due to the opportunity of the program "Looking for the Most Beautiful First Snow in the City". In the snow-covered mountains and cities, they work together to save others and untie the knots of the past. Their emotions are rekindled in the life and death tests and daily interactions.
However, just when they agreed to welcome the first snowfall together, which symbolized reunion, Lin Xue stayed on the top of the snow-capped mountains forever due to a sudden rescue mission. Finally, Xu Jinzhao received the message left by Lin Xue in the heavy snow: "If I are with Lin Xue today, we will grow together in this life." With this unforgettable love, she learned how to bravely spend the rest of her life alone.
