Lin Wuyou has been a "fool" for twenty years.
Everyone thought she needed to be taken care of for the rest of her life, including her brother Lin Shunsui. No one knew that she had carried memories of her past life since she was born, but was trapped in a chaotic mind, unable to wake up or pretend to be normal.
Twenty years after the outbreak of zombies, humans use zombie brain cores as energy sources, and hunters have become the most dangerous profession in the apocalypse. Lin Shunsui is the top among them. He is cold, powerful, and decisive in killing, but he has a pathological and repressed possessiveness towards his sister.
After turning eighteen, Lin Wuyou's mind became clearer day by day. But Lin Shunsui discovered that the secret he had hidden for many years could no longer be hidden.
After returning to normal, Lin Wuyou began to learn shooting, practice fighting, and kill zombies, transforming from a "sister" who needed to be protected to a hunter who could fight alongside Lin Shunsui.
This is not a story about a fool being cured, this is a story about a trapped person finally breaking out of his cocoon and driving a man who has been restrained for many years completely crazy.
Concept: Real strength is not to be trapped, but to still choose to stand side by side after breaking out of the cocoon; love is not one-way protection, but each other becoming each other's armor.
