The shop of Shen Zhiyi, an old restorer, is hidden deep in an old alley. Every old thing she handles is wrapped in the regret and tenderness of others, but she remains silent about her own past. Until starry sky photographer Lu Xingci pushed in the door, bringing a vaguely handwritten love letter from the Republic of China, as well as a sleeve full of evening breeze and starlight. He took pictures all over the world, but he only wanted to freeze the way she looked when she lowered her head and repaired old things; she guarded the store full of old times, but his heart was opened by his tenderness. The evening breeze in the old alley, the yellowed letter paper, the stars in the lens, and the love hidden in time all slowly fell to the ground in this autumn. They used old things as matchmakers and tenderness as contracts, turning other people's regrets into each other's perfection.
