Reader's POV
I walk down the hallway still trembling from what I saw back then. I've never seen Levi like that. He's like a very different person. That cold and dark expression and those fierce and deadly eyes, just thinking about that makes me shiver.I continue walking still having the feeling of fear inside me. I don't want to know what he's capable of, who knows what that could be and I'm positive that I won't like it.
"No, I must not get carried away by my fear. I'm a soldier, I must be strong." I told myself as I put my hands into a fist and tried to shake-off the early memory. "Now, I must go and help the other members of the squad in cleaning this castle." After that, I hurried my way out.
"_! Over here!" Petra called out from a distance as she waves her hands up in the air getting my attention. I quickly spotted her and run towards her direction.
"Petra!" I shouted. Moments later, I finally reach her and rest for a while to catch my breath. When I'm done, I brought my head up and looked at her. "So, how's it going? Need any help from cleaning?" I ask.
"Well, we're almost done but I think you could give Eren a hand in doing his job?" She said pointing the horse stable.
"Oh, cleaning that, it's fine. I can handle it." I gave her a smile and quickly move-out but Petra stopped me for a moment. "What is it Petra? Need something else?"
"Um, _, are you ok? Did something happen back then when you're alone with Levi-heichou?" She suddenly asked out of the blue. Her face is a look of concern.
"I'm ok Petra, nothing happened." I look straight to her eyes to make her believe that I'm not lying.
"Are you sure? When I called out for you, you were spacing out. I thought something happened since you're obviously thinking a lot. I'm just worried that something terrible might happen just like...before." Her voice is low and it seems like she's trembling. What could she mean by that? Did something bad happen before? Now to think about it, Petra and the others looked petrified earlier when Levi is extremely angry to Eren. Maybe this is the right time to ask.
"Petra, what is it? What do you mean by what happened before and may I ask why you and the others are petrified by just the sight of Levi being extremely angry?" I asked straight out but Petra shifted her gaze away from me. It's clear she is scared of something. I really wanted to know.
"Petra, please." I asked again. She finally looked at me but she's still a bit reluctant. She finally decides to talk but quiet as a whisper. "Well, I don't know exactly the details but all I know is Levi-heichou has a very dark secret. I think it is connected to his past but the only people who knew this are the ones close to him, mainly Commander Erwin, Major Hanji and Squad Leader Mike."
"A dark secret? Could you tell me some other details you know Petra?" I asked another time, feeling very eager. I know I can tell something about Levi's attitude just now if I can know just a little hint about him.
"Ok..One thing I know is he's a sadist. He, he enjoys punishing people and seeing them suffer to the point of dirtying his hands with blood. I, I remember back then..he, he almost killed a soldier out of anger because he betrayed him and disobeyed his order causing a lot of trouble for us. But the soldier was sorry for his actions still, Levi-heichou..." Petra stops up to that point. Her hands are trembling as she covers her mouth. Her whole body is covered with cold sweat and her expression shows fear. I think she is picturing something disgusting.
"P-Petra, what's wrong?" I comfort her in any way possible, stroking her back to remove her from her thoughts. "You don't need to tell me if you can't."
