An ancient book reveals a story of sadomasochism, and a woman creates a lifelong legend. The lingering love in the mortal world is always hopeless, and the idealism in the war is always regrettable. She thought she had found her lover, but in the end she discovered that it was the lover she longed for who pushed her off a cliff and forced her into a prison. A lifetime of loneliness cannot bring you any sweetness. Is this life worth it?
