Deep in the bustling and alienated city, there is an old bookstore called "Jingyu". The owner, Shen Qingci, has a gentle temperament, just like the books in the bookstore where time has been deposited. There is always a slight sense of alienation around him. He guards the bookstore and a past that he does not want to touch. Fire captain Lu Zheng has a cheerful and fiery personality, like a flame under the scorching sun. He is always at the forefront of danger. His life is filled with training and police dispatches. Under his seemingly rough appearance, he hides an unknown delicacy. An unexpected fire in a bookstore caused two parallel lines to suddenly intersect. Shen Qingci's calmness and Lu Zheng's enthusiasm collided and created wonderful sparks. One tried to get closer to the warmth, while the other hesitated in the frozen past. As they get along more and more, they discover that each other has unknown scars. Will they redeem each other, or will they be swallowed up by the shadow of the past?
