The angel Tino fell in love with the witch Yu Yuyao, and sacrificed all his spiritual power for her. Po Meng witnessed their past lives where they were sad but unable to love each other. In order to escape from the demon king who controlled her, Yu Yuyao reincarnated as Wan Xinyu, a woman from Jiangnan. However, she became a beautiful lady appointed to enter the palace, and began a love-hate relationship with Song Renzong. Wan Xinyu's past life memories were finally awakened. With the help of Po Meng, she came to the underworld and met the angel who suffered for her. Only then did she realize that she had always been deeply in love with the angel Tino. At this time, Xixia was at war with Song Dynasty, and during negotiations, Song Renzong was asked to marry Wan Xinyu. In order to repay the favor, Wan Xinyu agreed to the marriage, but committed suicide by taking poison on the way, hoping to reunite with Tino. But things were far from what she imagined.
