Sasuke found his long lost childhood friend who he forgot about and struggled when old feelings started to resurface.

Three months after Eren's death, Levi killed himself. They all pretended to be surprised--the rest of the world genuinely was, but in the Survey Corps, they all had their own witness of the strong love shared between them. Years later, Commander Armin Arlert decides that he can't let the story disappear forever, so he writes to each of his friends and former comrades, asking them to share their story of him. He's kept the letters for years. Yet, why couldn't he bring himself to write the epic?

Enter Eren: a young, hopeful, energetic soul, ready to start his summer in the rain without a glance over his poverty-stricken shoulder. Enter Levi: A perfect mismatch, a shady, unfeeling figure, still living too much in the past he's trying all to hard to escape. This is their story, fraught with imperfection and terrorized by circumstance. Their one brief-but-forever unforgettable summer in the rain.
