When the third corpse was delivered to Lin Wan's autopsy table, she finally confirmed the horrific discovery - all the dead had larvae of the same unknown insect parasitic in their brains. What's even weirder is that these people were all crazy about a certain object in their lives and were willing to sacrifice everything for it, including their lives.
"This is no ordinary parasite, it's a love poison." A mysterious man who calls himself Qi Mo suddenly appears and warns her not to pursue the investigation any further. As an expert in forensic entomology, Lin Wan never believed these claims of strange powers and delusions until she found traces of the same insect eggs in her own body.
As the investigation deepened, Lin Wan uncovered a thousand-year secret about the "Love Gu Family". It turns out that her family has been a love Gu master for generations and can control people's hearts through specially made Gu insects. And the long-lost "Atlas of Love Gu" is hidden in the jade pendant she has worn since childhood.
Now, all forces are looking for this map. Some people want to use it to gain love, some people want to use it to gain power, and some people want to use it to get revenge. When Lin Wan discovers that her inexplicable feelings for Qi Mo may also be caused by the Gu, she must make a choice: completely destroy this dangerous power, or learn to control it to fight against the dark forces who want to abuse the love Gu?
