Shen Buyan, a best-selling historical writer from modern times, traveled through time and met Lu Yuan, the "demon queen" of a generation that has left a mark on history. A two-way love affair for thousands of years happened on a timeline that ran counter to each other, so that he didn't know when she was in love, and she didn't know when he was in love. But if time and space are corrected, what will their future be like?
Concept: Perhaps when a drop of ink fades away thousands of years later, the cracks in the bronze mirror will eventually become a magpie bridge, allowing the "I love you" that have been misplaced for decades to fall into each other's eyes at the same time.
