She controls heaven, she plays with the locks of hell. One is the leader of heaven, and the other is the king of hell. They have the same identity, situation, encounters, and thoughts. However, because they are in different camps, they can always be enemies. When the gears of fate turn again, will it bring subdued war or greater fighting? When angels possess the blood of demons, and when demons possess the blood of angels, will it bring tears of angels or sighs of demons...
