AOT ships

Introduction

Hello guys this is hopefully going to be my first real story I am open for suggestions and I would like to apologize for any spelling mistakes because English isn't my first language, and I would like suggestions as to how to write the story so for example do you want it as a first person or a third person or a second person or do you want it like conversations between characters or how exactly and feel free to type any suggestion to the events as well

So as I said in the description of the story that the ships will be as following:

Levi x Mikasa (Levi isn't as old as he is in the anime, in this story he is 25 while the other recruits are 18)

Eren x Annie

Armin x Historia

and if you want any more ships like Erwin x Hange I am cool with it but they will be a side ship and won't be that important and probably won't have any development

So as you know the story occurs after the trainees of the 104th unit joined levi's squad and they'll live in a cabinet and they will carry out expeditions and that will bring them closer and from that the story goes on
