The main story takes place in the hometown of Zhuang Zhou. Seventeen-year-old high school student Li Yunduan is an art student studying painting. He is peaceful, loves plants, and has a soft spot for the romantic temperament of the number seven, but he spends his days dreaming about recreating the allusion of "Zhuang Zhou's Dream of Butterflies." One rainy night, I met a stranger holding a white chrysanthemum in his hand. He was barefoot and without an umbrella, and could not tell his gender. After that, I felt very sad. I lay in front of the window and was soaked in the rain all night. I had a dream, but I couldn't remember it clearly when I woke up. Later, he kept meeting by chance, only to find out that she was a girl with a mysterious temperament. The dream-like existence made him fascinated and disappointed, so much that he forgot about his dream and kept following the girl's footsteps. One day, a blue butterfly that looked like a "token" brought them together, and the two fell into a strange and colorful dream, with white robes and lanterns, nests of birds and butterflies, and in the dream... They woke up but still knew nothing about it. Until a certain coincidence, the blue butterfly lingering on the mulberry tree flew into the boy's eyes... And the mysterious girl was a lonely child who grew up in a dream, and her identity was confusing. Through the invisible web woven by the white-faced man, the young man who calls himself "Mirror", Zhou Li, the father with a doctorate in medicine and philosophy, the fanatical old man in a Mao suit in the lunatic asylum and the scrolls of records of his behavior over the years... It seems that we can vaguely see the beginning of the mirage of the past, as well as the meaning of "light" to some marginalized people. However, the secrets and prophecies hidden in the mirror turned into a softly chanted "Tarot Card", slowly unfolding the dazzling places of another world...
