Every book has a story, and every story has a soul who is willing to wait for it. Have you ever taken a closer look at the minutes and seconds when you turn the pages of a book, the feeling of friction between your fingertips and the pages, the fragrance of paper and ink? If you could have a pair of red devil eyes and be able to see and change these stories, would you be willing to pay the corresponding price and be willing to have these red eyes? Xia Liang, who was not born with a demon pupil, was forced to become a demon pupil. When she had the chance to return to being an ordinary person, she once chose to give up the opportunity just because she could borrow the power of the demon pupil and the soul master to save important people. When she had the opportunity again, she saw the flesh-and-blood stories and the life born for love, so she willingly became a red-eyed soul master, just to protect a book and the wisps of book souls. Unknowingly, those precious things that were lost in the past are once again possessed bit by bit.
