Training..

It was a normal day inside the walls, but Titans tried to get in. People screamed. Mikasa had to protect Eren and Armin. Suddenly she hat to save somebody else, since then everything changed....

(This is about Levi and Mikasa, because I really like them. I know that they are related, but they are not in this story. I learned English in school so If I make any mistake sry :/ )
