In the 20th year of the Republic of China, in the misty alleys of Suzhou, Jiangnan, there was an old antique shop called "Qingyan Pavilion". The heroine guards her ancestral shop and has had special powers since she was a child - when her fingertips touch old embroidery, old letters and other objects, she can glimpse the owner's unspoken thoughts or dust-laden past fragments. She has a gentle and reserved temperament, hiding her abilities deep in her heart, and just wants to live a stable life.
One afternoon during the rainy season, the male protagonist brought a frayed silver-embroidered handkerchief into the store, hoping to find its original owner. The moment the heroine's fingertips touched the embroidered handkerchief, she saw the foggy battlefield, the bloody setting sun, and an unspoken farewell. The male protagonist has a mysterious identity and a low-key behavior. He seems to be searching for some lost old object, and is surrounded by lingering melancholy and secrets.
The two bonded over old things, and the heroine struggled at the boundary between reality and fantasy. She was attracted by the mystery of the hero, but also feared the unknown risks brought by her powers. The hero gradually shed his cold disguise in the heroine's clarity and transparency. The mist and rain in the south of the Yangtze River, the agarwood in the old shop, the silver pattern in the embroidered handkerchief, and the remaining ink in the secret letter are all intertwined into a network in the splendor of the Republic of China.
They protected each other in rumors and redeemed each other in secret past events. When more old objects with superpower marks appeared one after another, they discovered that the fate of the two had been connected by a token from a hundred years ago. Those fleeting secret words are not only concerns that span time, but also affectionate confessions hidden deep in the years, guiding them to find the destination of love and truth in troubled times.
