At the end of the blue sea, there is an unnamed island, with the shadows of butterflies and the gentle sound of wind. Yue Lan fell into this place - he is a young painter escaping from reality and a lonely traveler of fate. The island is like a dream and a mystery, and the butterfly dance turns into fragments of memory every night, tempting to explore but also confusing. Yue Lan wanders between survival and fantasy, struggling to survive and obsessed with uncovering the mysterious "butterfly language" behind the island. The only companion on the island is a butterfly that whispers in the night, telling stories from the other side. Yue Lan must make a choice in the maze of fading time and soul - to reconcile with reality, or to remain in a mystery surrounded by dancing butterflies forever? This is an extreme challenge about self, memory and redemption, beautiful and dangerous. The secrets of the island belong only to those who dare to ask.
