Worried.

-It is okay, you can just forget about anything I said, as long as you are okay, I won't force you to do anything-

"Madam—"

"Oh shit!" Lena exclaimed and nearly jumped out of her chair. She threw her head in the direction of the voice and saw that it was only the butler. She patted her chest and relaxed. 

"It was just me, why do you look so scared, madam?" Butler Luther was also shocked by her action, he had almost thrown the book in his hand away when she reacted. Thankfully, his reflexes were good enough.

"Yeah, I am so sorry about that, Butler Luther" Lena apologized. 

"Madam, what were you thinking about that left you so distracted, I have knocked a couple of times before entering when you did not answer. Is something wrong? You can speak with master if you need something, madam" The butler suggested. 

"It's nothing" Lena flicked her wrist and smiled, "you probably did not knock loud enough for me to hear" she uttered and pouted.
