Nineteen-year-old Pei Xingye met an old friend he had not seen for three years near the ruins of the pheromone riot.
Twenty-nine-year-old Yan Chimu is no longer the gentle personal doctor he used to be - he has long hair tied up and distant eyes. The medicine box contains prescriptions that can stabilize the disease, but also hides old wounds that he refuses to talk about.
Pei Xingye thought that the reunion was the key to unlocking the past, but he didn't know that he was being drawn into a bigger whirlpool.
One is a genius who is tortured by illness, and the other is a doctor with perfect pheromones but a secret.
Old debts have not been paid, and new enemies have arrived.
When war breaks out on their borders, they must learn to work together - or lose each other forever.
This is not a romantic reunion.
This is a double-edged sword.
Cut open the darkness and cut open the human heart.
