Taking the friendship between Lin Wan and Su Nian as the main line, it connects the complete life trajectory of their youth together, their growing estrangement, their reunion after a long separation, and their time spent together. Through delicate scene descriptions, psychological portrayals and dialogues, it shows the sincerity and tenacity of friendship, and at the same time incorporates philosophical thoughts on growth, regret, and cherishment.
Purpose: True friendship can withstand the test of time and distance. After differences, misunderstandings and separations during growth, it can still return to its original intention and tolerate each other. Friendship is not about possession and binding, but a long-term companionship of each other's growth and mutual watching. It is the most precious and toughest emotional foundation in life.
