Ackerman's Steppes / Levi x Reader

Y/N (Ella) is a young doctor, living by Wall Maria, where scouts usually start their expeditions. She hates them for their obstinacy to keep fighting because it only leads their soldiers to their deaths. Ella is the one, who has to constantly bear the burden of seeing their brought back dying or already dead scouts.

One day, she is forced to take care of one of the scouts captains. Will she change her view on them after spending time with the one, who is partially guilty for all the things she hate?
