Levi had been through many things in his life. The death of his family, his two best friends... but he never expected his squad's death. He had entrusted his squad with his life, and in the blink of an eye they were all gone. He thought for sure he had no one. That's when Eren came along. Sure, he knew how this Jaeger boy was, but this time it was different... (There will be LOTS of parts in this that haven't happened or will most likely never happen in the anime and/or manga. SO DON'T COME COMPLAINING TO ME. But hey, what do yo expect from a fanfiction?)
