Klaus Barthel, a soldier for Paradis Island, lands in Marley as an undercover soldier to infiltrate the enemy.

While he's learning about the enemy and how they operate, he meets Pieck Finger, the Cart Titan while Klaus was writing home to Paradis Island. The two become very good friends, but Klaus starts to have feelings for her and starts to question his own thoughts. Does Pieck, the enemy of Paradis, feel the same about him?

Although Mikasa is the one AOT character that I will always be a fan of, I'm starting to like Pieck too. And that has to do with how cute she is with her signature tired eyes she would show in both the manga and in the anime.

Why not give her a try and a fanfic of my own?
