I don't know. I'm sure it was good for me but at the same time--my life would be very different if I'd ended up somewhere else.
[Since this is confession time.]
Maybe it's sort of like you saying you wish you'd never been born. My life would most likely have turned out differently, but the idea of you not being there brings me pain because you are so important to me. That's not something I would wish to change.
I would have never met Yuuki had I not ended up there. The impact on my life she's had I honestly don't know if that would be a good or bad thing. I just know I wouldn't be who I am today.
