The elf prince Elwin meets the dark flame lord Kairos due to a demon sniper attack.
In the name of "Dark Twin", Kairos invaded his life through the soul brand: the burning pain of the brand conveyed emotions, he whispered "feel my desire" in the middle of the night, and the collision of mental powers on the battlefield gave a glimpse of a thousand years of loneliness.
When the coalition tried Elwin for collaborating with the enemy, Kairos sent a provocative letter: "Evidence? Is the imprint of my soul and Elwin's soul obvious enough? PS. I'm thinking of you."
On a full moon night, Kairos used blood as a medium to hold his hand: "I die and you die." The moment the kiss fell, the two-color totem imprinted the soul - the fate of the twins of light and darkness was intertwined.
The ultimate temptation of the devil to the prince is just this: curiosity is the first step to fall. "
Purpose: Elves save the world?
