Lin Wanyi never thought that a late-night social software match would plunge her into a dangerous and pure relationship. Echo, that mysterious man whose head looks like a piece of burnt film, uses his gentle voice and poetic language to pry open the closed door of her heart little by little. From the initial casual chat to the late-night phone call, from the ambiguous dice game to the clumsy double row of kings, she gradually became addicted to his gentleness, but she kept escaping because of her avoidant personality.
However, the warming of her relationship did not bring stability, but instead made her desire for exclusivity and inferiority complex stronger. She wants everything from him, but is afraid that she is not worthy of his purity. When the conflicts came to a head, Echo's words "We are not suitable" brought the relationship to an abrupt end. Lin Wanyi finally understood that some feelings are like Klein Blue, so pure that it makes people panic, but also so short-lived that they cannot be saved.
This is a story about youth, growth and farewell. It tells the process of two lonely souls getting closer in ambiguity and then drifting apart in reality. Perhaps, some relationships are destined not to be perfect, but those late-night phone calls, gentle singing and clumsy companionship have long become the strongest touch of Klein blue in her youth.
Concept: Youth is a Klein blue dream, so pure that it makes people panic, but also so short-lived that it cannot be saved. We get close in ambiguity and drift apart in reality, and finally learn to let go and grow.
