Lin Nianchu and Su Yuqing, childhood sweethearts, have been separated for more than ten years due to a trick of fate. She became a designer in the north, and he became an accountant in the south. They were both wandering in the city but had no home. They reunited due to work opportunities, went from estrangement to acquaintance, and faced career crises and family responsibilities together. In the end, he chose to return to his hometown in the south of the Yangtze River, turned regrets into the courage to stay together, and restarted his life under the sycamore tree. This is a story about time, choice and destination - some parting is for a better reunion; some turning around will eventually meet the eternity in the dim light.
