Su Wanxing from Xingluo Town in 2022 and Lin Yu from Star City in 2025 exchanged bodies on the starry night of the 15th day of the lunar calendar due to astrological bonds and a pair of old pocket watches. From strangers running together to tacit companionship, memories slowly fade away due to time and space barriers. When Lin Yu discovered that Xingluo Town was about to encounter the tragedy of a falling meteorite, and that the matter was closely related to the death of his mother, he traveled across time and space to pursue the truth. Finally, when the tide of stars falls, the two resonate with each other and work together to save the town, retrieve their lost memories, meet again under the stars in the sky, and continue to write the fateful bond that spans time and space.
