The grocery store at the entrance of the old alley has been there for twenty years. The owner Lin Wan sells snacks, tobacco and alcohol during the day, and takes in frustrated people who are lost at night. On a rainy night in late autumn, a soaked boy pushed in the door with half an old photo in his arms. The girl in the photo had exactly the same features as Lin Wan. It turns out that an accident separated the two people ten years ago. The young man wandered around for several years, searching the whole town with scattered clues. The candies on the shelves of the shop and the yellowed post-it notes on the wall are all tiny memories of the two of them when they were young. Lin Wan originally decided to put the past behind her, but as they got along day after day, she slowly untied the knots in her heart that had lingered for years.
