The state between dreaming and waking is called sleep, and the Sleep Realm is the place between dreaming and waking.
People often enter the Sleep Realm without knowing it, because its fundamental rule is erasure. Unlike the Dream Realm, memories from here are never brought back to reality. That is why people know about dreams, but not about sleep.
Song Weichen is an anime girl who works as a virtual persona for a digital entertainment company in the real world. After a sudden accident, she becomes trapped in the Sleep Realm and cannot return to reality.
There, she meets a man who calls himself a grudge-breaker: Mo Tingfeng, the Lord of the Dust-Warding Office. Through a series of mishaps, she becomes the office's second-ranking grudge-breaker, known as the White Robe, outranked only by the Lord himself. With no cultivation or magical powers, how can this modern novice possibly handle such a responsibility?
Neither of them knows that their meeting is the beginning of a deliberate conspiracy. A thousand years ago, they were already caught in a tragic romance that brought them to the brink of life and death. As the past is gradually unveiled alongside the future, what will she choose?
People are destined to remain prisoners of emotion, and human feelings are the greatest destabilizing force in the Sleep Realm. When passion stirs, it can lay waste to everything. If it brings about a fall into sleep, all creation will face catastrophe...
Theme: All human suffering stems from emotion. Love becomes obsession, and obsession becomes demonic. Not even a thousand years or countless lifetimes can break it, and grudge-breakers themselves are no exception. In the end, those who save others must save themselves, and those who guide others must also find their own way. Break grudges and release obsessions, let go of what must be left behind, and restore peace to the world.
