Seven complicated cases and seven original sins at the bottom of human hearts have tied two unrelated guys together: Lan is calm and calm, but has no care for human beings, but has a different focus on Xi; Xi is hot-blooded and brave, hoping to protect human beings, and unknowingly gets used to Lan's company. They are ice and fire, one is good and the other is evil. Perhaps this encounter has been destined for a long time. However, as the bond between them becomes deeper and deeper, they actually discover that there is a dark conspiracy between them that can never be reconciled...
Purpose: Even if human beings engage in various uncivilized behaviors, human beings are still worthy of protection.
