Xie Xiang is the fifth generation descendant of the "Wenxiang Pavilion" incense shop in Jiangnan. He has been with Xiangni since he was twelve years old. That year, Shen Long, the down-and-out young master of the Shen family, came every day to beg for the scraps left over from making incense, saying that he wanted to smell the incense for his sick mother. The boy lay on the counter and watched her kneading, pressing and drying the scent. He secretly learned the trick of "relaxing and twisting to retain the warm texture of the scented material", and he also kneaded her into the softest corner of his heart. But the difference in family status was like a crack in the dark, causing the two reserved and timid teenagers to stay apart at the ferry for ten years. Xie Xiang inherited his ancestral skills and became a well-known incense brand craftsman in Jiangnan. Shen Yan, a Jinshi of high school, returned home in fine clothes. When they reunited, the room was filled with agarwood, but the guests did not dare to recognize each other across the room. They take incense as their trust and taboo, and knead their lovesickness into tens of millions of incense sticks. If they knead it too tightly, it will become rigid and stiff, and if it is kneaded too loosely, it will fall apart and become shapeless - just like this deep love that they never dare to use force and are unwilling to let go. When Xie Xiang searched for strange fragrances all over the world to restore the ancient "Agarwood Fragrance Brand", Shen Long silently found the last Xizhu Qinglian for her, but quietly left his post on the day when the fragrance was completed. Xie Xiang held the incense card with a fine crack in it, and finally understood: some fate is like incense crumbs, you only know how precious it is when you crush it into pieces, but if you can't fight it back, you can't fight it back after all.
