Title: Father's Theory

Y/n's POV

I just joined the Cadet Corps. I'm really excited. I can't wait to join the Survey Corps.

Me and this guy Erwin got partnered together for training. He was a really tall and big guy. Of course, I whooped his butt

"Where did you learn to do that?" He asks me. I shrug my shoulders with a smirk. He gives me a slight glare and I laugh.

~3 years later~

Me and Erwin had began dating about a year ago. After our little training match we got super close. He told me about his father's theory and honestly I think his father was right. Anyway tonight is the night where we pick our regiments. Of course we both picked the Survey Corps.

After the ceremony thingy we were officially scouts. I hugged Erwin

"We did it! We're finally scouts!" I say happily. He hugs me back

"Now we can find out if my father's theory was correct" He says

~Time Skip~

We've been losing a lot of people on our expeditions recently. What the hell is Shadis doing? Erwin came up with a plan to minimize casualties but Shadis denied it. Even the scouts are loosing hope in Shadis. I've heard people saying they would rather have Erwin as their commander. I think Erwin being commander would be awesome.

We were all called into a meeting

"I'm resigning from being Commander" Shadis says. Me, Mike, Erwin, Moblit and Hange stare shocked

"Who will lead us then?" I ask

"I appoint Erwin Smith as the new commander" Shadis says

"I accept" Erwin says. They finish up the paperwork and now Erwin is officially commander.

I'm so happy for him

"Hey Y/n, come by my office later" He says. I nod and walk away

~Later~

I knock on the door

"Name and business" Erwin says

"Y/n, you wanted to see me" I say

"Enter" He says. I open the door and close it behind me. I then sit down on a chair.

"What did you want to talk to me about?" I ask curiously

"We're through" He says. My eyes widen

"What do you mean?" I ask

"We're through. Our relationship will now be strictly professional" He says. My heart began to hurt but I kept up a mask and remained calm on the outside

Why would you do this?

"What brought up this sudden change?" I ask calmly

Did I do something wrong?

"I am now commander. It would be inappropriate for me to date someone of a lower rank" He says

Tell me the truth

"And?" I ask. He sighs

"Proving my father's theory and saving humanity is my priority. I do not have time for a relationship" He says. I nod

"I understand. Is that all?" I ask

"Yes that's all. You're dismissed" He says. I get up and walk out. I walk calmly to my bedroom and close the door. I lean against the door and fall to the ground. I cover my mouth as I begin to sob

~Time Skip~

After we broke up, our relationship was professional but eventually we became friends once more. That's all we would ever be. Friends.

~Years Later~

Apparently there are people who can turn into titans. Erwin lost his arm a few months back trying to get Eren back. Many people are dead...

I'm next to Levi, he's about to turn Armin into a titan so he can eat Bertholdt

"STOP!" A guy yells. We all turn to see a guy holding Erwin in his arms. He sets him down on the roof. My eyes widen as I rush to his side

"Erwin! Erwin!" I yell as I look at the state he's in. Tears stream down my face. Levi ran over to give Erwin the injection but Eren started yelling about Armin. I just stared at Erwin with teary eyes. His eyes slightly open

"Erwin! Stay awake!" I yell as my voice cracks.

"I'm sorry... I love you... I always did..." He says weakly as he closes his eyes once more. I began crying even more. I wasn't crying because he told me he had always loved me. I was crying because I knew it was time for him to rest

"HURRY AND SAVE THE COMMANDER!" Floch yells

"Stop... Erwin... Erwin can finally rest... Don't bring him back... Let him rest in peace.. please" I say as I continue crying. Levi nods as a tear streams down his face. He injects Armin. Armin became a titan and he ate Bertholdt.

~Time Skip~

I'm at Erwin's grave. After he died, I was appointed Commander.

"Being a commander is hard work. I don't know how you did it Erwin. We finally got to the basement. Your father, he was right. I asked Queen Historia if I could read you the books we found. If you can hear me, you better listen well.. cuz I'll only say... it once" I say as a tear falls down my face. I begin reading the book to his grave

~Time Skip~

We're finally gonna see the ocean. We finally got permission. We're almost there actually.

We stop riding our horses and walk to the shore. I take in the view and I smile.

"The ocean its so pretty" I say

"I'm sure Erwin would've liked it" Levi says. The color of the ocean reminds me of Erwin's eyes. A tear rolls down my face as I smile

"Yeah he would've" I say
