Guardian of the Godly Death

He is a wizard who has been sealed away from the power of destruction. Destiny made him become another king. When he became successful, he suddenly turned around and left, disappearing into the legend of the world. Just because the person he wanted to protect for the rest of his life chose to marry someone else. But has he really given up? The hard work that turned her black hair into white hair was exhausted, just because he was actually always by her side.
