Love was originally a lotus fairy in the sky (Yao Xiang) who fell in love with the Eastern Qing Emperor (Cang Yuan). Yu Zi, the daughter of the Emperor of Heaven, could not help but admire the Eastern Qing Emperor, so she revealed their love to the Queen Mother. The Queen Mother used her power to separate the two alive. Yaoxiang was forced to drink Meng Po soup and entered the mortal world to undergo calamity. She was reborn as a double-hearted person named Luofu, who could see into people's hearts and enter the dreams of others. And a drop of tear from the corner of her eye also fell into the world, turning into Nalan Ruohe, a tearless woman. Cang Yuan then dug out his heart and fell into the mortal world with Yao Xiang, and was reborn as the unintentional person Shen Qingyi, who was ruthless because of his unintentional nature. A drop of blood in his heart turned into a bloodless person named Jingchu. The four people experienced various aspects of life in the human world, gained insights into all kinds of people's hearts, and solved many strange cases. In the end, they successfully survived the disaster and returned to heaven.
