Because
Disclaimer: I don't own Yu Yu Hakusho.
You know how sometimes when something comes over you, something that's so persistent, so demanding, that you couldn't possibly NOT do it? Well, that's sort of what happened to me that night.
Well, not exactly. Because what happened to me--- what happened between us--- started way before that night. Maybe it was the day we first met, or when we became friends, or.........when you died, and miraculously came back from the dead. Whatever it is, the seeds were planted way before that night.
I know that what you are now----- what you're doing, what you're life is, has no room for me. You only try to give me a place, but eventually, I'll fade to the background, merely a distant memory. I can never be a part of that, like Kuwabara, Hiei, Kurama, and even Botan, are. Because I'm not like that----- I'm not like you. I'm human. You're a human, too, I suppose, but.......you're special. I knew that all along.
But, I don't know.....I realized that I couldn't be there, not anymore, but I so wanted to be. I wanted to be with you.
So, maybe that's why I came up to you tonight, prbably not 100 sane and more than a little drunk. I came to you, clinging to a desperate hope that you would understand---- you would sympathize. I hoped that you would stay.
So I came up to you at a party in Kurama's house, swaying a little. My words were slurred, but you understood;
"Listen, Yusuke, you jerk, we've been through a lot together. Not like, the 'Spirit Detective' crap you do, but just us. When we still had normal lives. I want us to be together, because I care a lot about you. But I also know that you don't belong here with me, with humans. You're special. So go do whatever you do, but come back after three years to let me know you're still alive. And maybe come by once in a while, so I know you're there. Ok?"
It was at that moment that I chose to fall into your arms, but you were smiling. At least, I think you were. But I know I did the right thing.
It'll be hard to wait for you, but I know that I gave you all that I could. And, because I love you, I know..... that you're worth it.
