On the border of the mutated forest, the former brave Senyu returns alone, carrying a secret that no one knows. He disappeared during an exploration mission ten years ago, but now he has returned to his hometown with a whispering stick and a pair of strange-colored pupils. The forest is no longer the familiar sanctuary, with trees growing into a maze and animals gazing at humans and whispering. Legend has it that Senyu has signed a contract with the forest, but in reality, he must make a choice between the will of the forest and the fate of mankind. The villagers see him as a monster, the exploration team sees him as a key, and he just wants to uncover the truth about the mutation in his lost memory. The return of a brave man is not a triumph, but a struggle between the boundary between self and nature. In the mist and thorns, can Senyu use his own way to reshape the ancient agreement between man and the forest?
