The genius boy Lu An has been out of tune with his surroundings since he was a child. He is addicted to the dying Nahua language and meets a mysterious friend on the Internet. On his eighteenth birthday, the other party left behind a necklace with gray and black feathers and a Nahua phrase, and then lost contact completely. Lu An traveled to the homeland of the Nahua language. On the way, he fell into a strange world, experienced illusions, and even transformed into a bird. After waking up, the necklace disappeared, and the past seemed to be illusory and real, leaving only the mystery of the "two birds of the heart" lingering in my mind.
Concept: Loneliness and Soul Resonance: In reality, Lu An cannot integrate with his peers and lives on a spiritual island. He and his anonymous netizens do not rely on their real identities, but only rely on language and spirit to communicate with each other. They write about soul-level confidants, a pure connection that transcends appearance and distance.
