38-year-old Lin Wan is an independent owner of an urban jewelry store. As an older unmarried woman, she's long been used to living alone. One late night, a video call suddenly pops up on her phone—a little boy on the screen holds the keepsake necklace she's hidden for 20 years, calling her "Grandma" in a sweet voice. He claims to be Xiaotang, her grandson from 20 years later, and says his dad Gu Ye is working overtime in the café downstairs. Lin Wan thinks it's a prank until the boy recounts her secrets: finding a tailless cat at 19, hiding cat litter under her bed only to have it confiscated by the dorm supervisor—things only she knows. Half-convinced, she goes downstairs and meets Gu Ye, a programmer in a plaid shirt with a silver star necklace in his pocket—the exact match to her first love's token. It turns out that 20 years ago, Lin Wan lost her biological son due to a misunderstanding, and the video from her future grandson is here to help her unravel the past and reclaim the mother-son bond she missed.
