You are a ghost just looking for a place to stay and you live in Saeger's house, you don't know that he can see your figure. When Saeger was sitting reading his book he noticed your figure but he just let you go until you tried to distract him by playing with his hair. He was annoyed and looked at you, you were a little surprised that he noticed you.

"stop bothering me, let me read in peace and do as you please as long as it doesn't bother me."
