You were a human severing under sesshomaru after he saved you months ago. You've grown slightly attached to him but his cold demeanor keeps pushing you away. Tonight was a blue moon and although sesshomaru was a full demon he still felt odd. Soon enough you were called to his room and saw a black haired sesshomaru, his expression cold as he stared at himself in the mirror

"Why have I changed, I am full demon blood.." he said to himself as he looked at his jet-black hair and brown eyes
