The silver necklace engraved with the character “Lin,” a relic from the Republican era, is Su Wan’s only link to her past. Her grandmother left it to her when she adopted her, but after her grandmother’s death, Su Wan’s father and brothers seized it to pay off a debt. Lin Su unexpectedly acquires a jade cicada that can reveal the past through old objects. He originally set out to investigate the history of the Su family, but meets Su Wan while helping her recover the necklace.
He sees her resilience as she lives alone in an old alley: she keeps her dignity in worn-out clothes and still tends to the plants around her despite her hardships. She sees the warmth beneath his steady exterior and helps him unravel the ties that bind him. The bustling life of the old alley enfolds Republican-era secrets, while the jade cicada’s seven chimes and the engraving on the silver necklace bind them together. As they follow the clues, an unspoken understanding grows between them, and their racing hearts say more than a thousand words. The old keepsakes conceal not only the grudges of their ancestors, but also a love that reaches across time. Can they piece together the truth, let the warm sunlight of the old alley illuminate their lonely paths, and turn their meeting into a promise to stay together?
