Actually, it would be either eto or ano.
And your story is great! I'm an aspiring writer too, and I found it to be particularly well written. Good job.
The only problems I noticed were things like not spacing in between words and parentheses [this(is not correct); this (is correct)] (which might actually be correct, but I learned differently), and that you forgot to include apostrophes at times [such as in this sentence: "Thus came the daily confirmation of his brothers obsession."; There should be an apostrophe in "brothers," like so: "brother's"].
But like I previously stated, it was great.
