I'll try to make parts longer for you. Like, maybe, splitting a chapter into three to five.

Chapter 1:
Who am I?
Part 5
"Well," said the shiny Umbreon, "I'm Chris."
"Nice to meet you," I said. "Know anything about my past?"
"Will you trust me?"
"Will that be possible?"
"That's why I like you so much. Anyways, we met a couple years ago in that direction." He pointed due south. "You were still an Eevee at the time. A wild and rambunctious one at that. But then again, so was I." We both kind of chuckled at this. "We grew as close as brothers over the next couple months. And even though you can't remember any of this, you're still my closest friend."
I let that sink in. [He does indeed seem to have a brotherly quality... If he's going to be this nice to me, I may as well smile and be nice back.]
"Sorry that I doubted you. More and more Pokémon have been turning aggressive lately. Nobody has any idea why."
