Wondering about things always makes you slightly paranoid. Therefore, I have never wondered what life would be for me if Haruhi wasn't in this world. I have never wondered what life would mean to me if I didn't have all of the troubles that I secretly enjoyed. That is, until I experienced what these two subjects really felt like. That world...was inhumane. It was cold, and if God was watching me at that very moment for three days, I'm sure that he would've laughed to the point in which he was crying. It felt aggravating, not knowing anything about that world that was now normal to me.
So, I have not one regret in reversing the world to its original state. My only concern was how much I had come to rely on Yuki Nagato. I became so reliant to the point in which I couldn't even notice her problems, or her changes. I thought that everything would be okay, so long as Haruhi was in check. I didn't see her struggles, and I was blinded by my own 'misfortune'. Haruhi wasn't the problem anymore. I was. And I alone.
And experiencing something that you can wonder about, can make a person change. And this made me come to one realization; my life, with or without Haruhi, is upside-down either way.
