The story takes place in a quiet fishing village by the sea. The girl Agui (played by Li Yunyun in her childhood and You Xin in her adulthood) has seen the world differently from others since she was a child - she is color blind. Although this is destined to make her incompatible with the reality around her, it did not make her lose hope in life. She took the multi-colored glasses given by her father and discovered the sky of different colors. Like her, her most admired cousin Axian (played by Lin Bohong) is full of yearning for life. Axian told her that there is a color-blind island in the distant South Pacific, and the islanders are all people who can't distinguish colors like Agui. The beautiful story comforted Agui and made her feel that she was not alone, and therefore she developed a vague love for Brother Axian. Axian's secret is that he is immersed in the world of homosexual love. They are all guarding each other's secrets and planning to leave the small fishing village where they live and go to a free paradise where they will not be regarded as aliens.
