Jaejoong was a light bearer, but for some reason..he has the memory of Altheia, the deceased queen of darkness..she died believing that their is a chance to reconcile the light and dark world.

Yunho, live in the darkness for years, he doesn't know what keeps him alive after the most important woman in his life died..in the deepest part of his heart he seeks forgiveness for not protecting her, covered with hate..he engulf most of the land parts with darkness.
