The heroine, Qin Banmeng, is a flower spirit formed from sorrow and the essence of a peach tree. She has lived from the Eastern Jin dynasty to the modern era. Across the long river of time,
she was first his secret lover, but he never chose her wholeheartedly.
Later, she accidentally became caught up in a strange series of events and met Ran Bu, the person destined for her. She then witnessed many people making choices they had no choice but to make in turbulent times: separating from loved ones for the sake of their futures, pretending to be friendly for profit, and regretting their choices after their desires spiraled out of control.
Then she witnessed a love unlike the others, and the regret of being too old.
