So you've seen most Human in Equestria stories, mostly bronies doing the things 'we' wish we could do. You may think this is another one of those stories. I won't say you're right or wrong. That's your opinion. Then again, this life is going to get crazy all because of what one little chart (or in this case, multiple different charts) has to say for our protagonist.
And he has no idea whatsoever.
So join him in whatever craziness that the charts have to offer him, and check to see what yours would be if YOU were using the same chart.
