Armin's fear of being a burden haunts him; it pushes him to train harder than ever. When his quick thinking during a crisis fails to convince him of his ability, Eren decides to adopt a new mode of persuasion to help relieve Armin's fears. // Canonverse (training arc) focusing on the progression of Eren and Armin's relationship. ( Although this is technically canonverse, I've aged everyone up a few years.) This is a cross-post from my account on Ao3, originally posted during summer 2017.
