Eren was in the Captain's room, looking over all of Levi's things. Finally, he opened the desk and found a small book like journal.

"Hm?" Eren opened it to the first page, and saw the date.

12/05

Mom has been getting worse lately. She hasn't been eating right, and whenever there's food, she gives it to me and tells me to eat. She always tells me I'm a growing boy and I need to eat. But honestly, I don't want to. Mom isn't healthy and she needs help. But there isn't any doctors that are willing to help. Mom told me that one day I'll have to learn to how to take care of myself. I already have to do that.

- Levi

Eren could barely read the hand writing, which was a sure tell sign that this journal was written when Levi was a kid. He decided to keep reading

30/06

Mom died today. A strange man came into the house too, claiming to have known mom. He said he'd take care of me for a while and teach me how to survive. His name is Kenny. I don't know whether I should trust him, or not. But If he's going to teach me how to survive, then I guess I'll have to.

- Levi.

12/08

Eren knew by the handwriting that this entry had been written a few years later.

Kenny has taught me a lot of things. Yet, I think he still has more to teach me. I can't find him anywhere though. I got into a fight and he just, walked away. I've been searching for him for hours and I haven't found anything. I'm guessing he gave up. Almost everyone does when it comes to Levi Ackerman.

- Levi.

The next few entries weren't anything useful. But one did catch Eren's eye.

5/04

Isabel and Furlan had been unusually quiet this week. Maybe because they're afraid that we'll get caught with the ODM gear? That's not it. I know it isn't. I'm actually curious for once. Isabel had joined Furlan and I, a few months ago and had gotten the hang of the chores, and the ODM gear quickly. I'm proud of her, although I wouldn't say it outloud.

- Levi.

So. We got caught. This guy named Erwin Smith and the Survey Corps got to us. Erwin and his big bushy eyebrows, man I hate that asshole. But, he cut me, Furlan and Isabel a deal. We had to join the Survey Corps. Which was perfect because of the job we had to do. If we joined, Erwin would forget all of our offenses and shit. It was a two for one deal in my opinion. Actually, we really didn't have a choice.

- Levi.

14/09

Isabel and Furlan were killed. We went on our first ever expedition, and I left for not even 10 minutes, and they were killed by a Titan. I knew they shouldn't have went. I made the choice to stay with the Survey Corps, and I won't ever regret this choice. This is what I have to do. For Isabel and Furlan. For mom, and Kenny too. This is my choice. With No Regrets.

- Levi.

Eren was sitting in Levi's chair at this point, tears falling down his face. He never knew about any of this. There weren't many entries, but Eren knew Levi had gone through tough times. The next entry he read didn't have a date, the same goes for the next ones after it.

The cadets this year are proving themselves worthy. Found out this one boy, Eren Jaeger, is actually a Titan. Ain't this fucking fantastic? The kid basically can regenerate, and grow limbs back like some fucking lizard. It's disgusting. He's caught my eye, which, I think is a good thing. He seems useful. I hope Erwin will put him to good use.

- Levi.

My squad got killed. Every single one of them. Well except Eren. Why do I always lose the people that I care and love for? Why am I even surprised? I'm numbing up inside.

- Levi.

Turns out that the female Titan was one of the 104th cadet graduates. Annie. Eren fought her in his Titan form, and beat her. But the worst part is, Annie trapped herself in some kind of hard crystal. It's basically unbreakable; which annoyed Hanji. And another problem. There's a hole in Wall Rose. But that's not the problem. There's a Titan in the wall. And we have no idea how it got there. The only person who knows anything about it, won't speak up. It really pisses me off.

- Levi.

Well, Mike, Nanaba, and a few others have died. We've found out that there's a beast Titan now. And Ymir is a Titan too. And turns out Christa's real name is Historia and she's royalty. What a turn of events.

We're going on a new expedition. I might not make it back. I've been feeling more numb than usual. I actually cried, for the first time in a while, last night. It hurts, knowing everyone you care for is dying left and right and you don't even get a chance to say goodbye. Maybe it's best that I don't come back. The only people I have left are Eren and Erwin. I already feel like I'm losing both of them. Maybe it's just the depression, and anxiety acting up again. I can't give up just yet. Giving up means that humanity is lost. I'm humanity's strongest, and I have to stay strong for the remaining soldiers in the Survey Corps. Sometimes I wish they didn't expect me to stay strong. I want it to be ok to cry. But I know it's not. If I cry, they'll realize that I'm not strong. I would have failed them.

- Levi.

That was the last entry. Eren closed the journal and wiped his eyes, he felt guilty for not helping Levi. He never knew Levi felt like that. I'm not even sure if anyone even did. Eren knew Levi was strong on the outside. But what about on the inside? Was Levi everything he made himself out to be? Was he everything everyone said he was?

"Eren." Mikasa poked her head into the room. "Armin and I are going to get something to eat. You should come with us."

Eren got up and followed Mikasa, closing the door to Levi's now empty room; and the journal sitting neatly on the desk, as if it was never touched.

"You've given me more than I could ever ask for, Captain Levi. I hope one day I can repay you, for saving me that day." Eren looked at the floor on his way to the dinning hall, a tear trailing down his face and falling to the floor.
