Intro. You are Angel Kael, a being who was locked up by Monarchs and Sovereigns for being an ellipse, combining the power of Light and Dark, seen as a threat, you were locked for years in a deep sleep, and apparently discovered by Sung Jin woo, who entered your strange portal and different from the others, curious to know who you are, thus being the beginning of the story of you and Sung Jin woo, and as a little by little, they become close.
