Half and Half (Oblivious!Eren x Reader x Slight!Yandere Levi)

Delay

"Cadet, pay attention up here please, this is extremely important." The instructor called out as he tapped the chalkboard, catching your attention from being dazed. 

"Ah, yes. I'm sorry." You nodded as you gave the instructor an apologetic bow, leaning in forward with your upper body, allowing the man to continue as he drew a circle on the chalkboard. 

"As you know, if we happen to spot an aberrant, you're given the cue to signal a black flare so that you'd notify other squads around you. We will be staying together in a perfect formation just like every time. Squad Levi will be leading squad 133. Squad 133, be sure to take notice on any danger nearby. It could cost your life if you're not careful. There will be no trees to attach our gears onto so you all must be prepared. As you may know, we can't determine aberrant titans. Their actions are unpredictable and..." The instructor looks over towards your direction, catching your face, inscribed with boring on. He squinted his eyes and frowned.

"Cadet!" He calls out to you again as you snapped out of your thoughts.

"Y-Yes?" You were startled by his sudden shout. 

"You seriously don't know what's going on?" He waves his hand around, tired by your dumbstruck.

"I uh..."

"I'll have to report you to Corporal Levi. Maybe he can explain this expedition---"

"Nonono! I completely understand this! Squad 143 follows squad Levi and we're able to use the forest to our advantage and---"

"I don't recall saying such nonsense." The instructor sighed as he crossed his arms, tapping his foot impatiently.

"We'll talk after this discussion." He groaned as you stared down in shame while your subordinates watched you in humiliation and defeat.

Strangely, you've been serving the Survey Corps for almost three years now. You've been through the same thing everyone has gone through, loss and sympathy. You've gotten so used to seeing your subordinates' corpse, it was like a daily routine for you. You stopped crying after two years. You stopped being half the human you once were as a whole, due to the fact that the titans you've eliminated over the years were humans, just like you. But there was nothing to stop them. No cure, no miracle. So how do you understand a titan when all they do is eat during the day and sleep during the night?

When class ended, you walked up to the instructor, bowing to him again and apologizing for your stale behavior. 

"I don't want your apologies. A thousand times you've been a little.... spaced out. Is there something wrong, (Name)?" He asked as you shook your head.

"No, I've been... Thinking too much, that's all."

"Well, I hoped you were thinking about this, but..."

"Yes, I'm very sorry." 

"Ah, there he is. Right on time." The instructor says as you turned around to hear the door slide open.

"Brat." The voice spoke with a click of his tongue.

As you turned around, you felt a slap to the back of your head with a paper rolled into a cylinder.

"Ow...." You rubbed the pain you have earned from class.

"Your head is hollow. Pay attention in class, you brainless brat." The short man slaps your head again, only this time, a little softer than last time.

You nodded in response, cradling your head as the man approached to the instructor.

"Lance Corporal Levi. Good to see you." The instructor greeted.

"I see that she hasn't been focusing on the expedition." Levi scoffed.

"Yes. I'm afraid that she might not have what it takes to go on this one--"

"I have what it takes! I swear! Just because I survived for this long, it doesn't make me a rookie!" You burst.

"If you do, you'd be paying attention to our procedure that we recently discussed, cadet." The instructor stated.

"I know what I'm doing!" You claimed.

"Don't raise your voice to your superior, brainless brat." Levi lifts his arm to strike you again but you covered it, forcing him to retreat instead.

"I honestly do. Besides, If I die, I wouldn't be much of a loss. You said it yourself, Corporal." You rubbed your hands as the instructor stared at you.

Levi didn't want to respond to your statement. Actually, how would he? Sometimes he didn't mean it. Sometimes he did.

"Come to my office, now." Levi demanded as he grabbed your arm and dragged you away from the classroom.

"Hey, Hey! Easy!" You tried to release your arm from his grasp but he was stronger than you to clutch onto you.

"What do you think you're doing? Are you even in your right mind?" Levi turned to you, letting you go as you jerked away.

"What are you talking about?" You rubbed your arm that was stamped red, outlining Levi's hand that was now imprinted like a tattoo.

"You've been absent-minded since yesterday. What the hell's going on?"

"What!? That's insane---" You shrugged it off and walked away but Levi stops you.

"You're hiding something. What the absolute fuckery is wrong with you, huh?" He nods at you once while saying that last word.

"I don't know, sometimes I just... Doze off, ya know?" You shrugged again.

"That's not a valid answer, cadet."

"Corporal, trust me. I know what I'm doing on this expedition---"

"Look, if anything happens to you, it's on me. Understand?" Levi warned you.

"I got this, Levi. Besides, what could go wrong?"
