In stories, there has to be an end. That's the difference between stories and real life. In real life, you just... keep on living, until you die.
But I didn't die, and neither did Kirino. We didn't break up either, and although we were constantly arguing and squabbling, we also never stopped loving each other.
Our life, however, was very difficult. None of our old friends ever accepted us as a couple, and it was difficult for us to meet new people- too many awkward questions about our relationship. So we mostly just kept to ourselves.
Kirino finished high school, and got a job as a saleswoman. She was quite good at it- she basically bullied the customers into buying things. But it was stressful and exhausting for her. I continued my boring job at the konbini, eventually getting promoted to manager. We had enough money to live comfortably, but it wasn't nearly enough to satisfy Kirino. She was always resentful that she couldn't spend money like when she was a teenager, collecting money as both a fashion model and a hit writer. She often said things to me like "why are you still working that dead end job? Go make something of yourself!" but I was never able to find anything better. Neither of us ever went to college.
Kirino continued playing eroge. But, over time, she started to enjoy them less. I think she just plays them out of habit, now. She's always complaining about how the new ones are so formulaic, and not as good as the ones she played as a teenager. In my opinion they're all equally stupid, but I don't dare say that to her. She mostly skips past the H scenes now, and doesn't gush over the heroines- she just wants to clear them as quickly as possible.
Mostly, I lead a very quiet and boring life. I work until I'm too exhausted to think properly. I go for drinks at dive bars with other wage slaves. I watch sports on TV, even though I never play sports myself or go to the games in person. I dutifully cheer for my local teams, because that's what normal people do. Then I come home, and just try to avoid fights with Kirino.
Even now, when we are both in our 40s, Kirino still looks amazing. She has the same cute face and perfect figure, it just has a more mature expression. It still gives me the same thrill to see her lovely body, to feel her soft touch, and to hear her call me "oniichan". I still can't say no to any of her demands. My only real joy in life anymore is to see her smile. I wish I could make her smile more often.
We never had kids, of course. We were very careful about that. She takes pills, and I got a vasectomy. Still, it makes me a little sad. I think children are the biggest part of "normal life" that I'm missing out on. Kirino says she's happier not having kids ("Pregnancy would totally ruin my figure! Kimoi!") but I think she's also a bit sad about it. And it makes for an awkward conversation whenever someone asks me about it. "Hey, you got a girl, right? How come you never had kids?" Well, that's just one more reason why I try to avoid getting close to anyone.
I haven't spoken to my parents at all, not since that day in court. I don't think I ever will again. Maybe I'll go visit their graves after they die, but not until then.
I did speak to all of our former friends a few times. But it's not the same. We just exchange bland pleasantries. Then they ask if I'm still together with Kirino, and I admit that yes, I am... and they end the conversation quickly. I think most of them are in relationships of their own by now.
When I lay it all out like this, my life sounds rather bleak, doesn't it? I have to admit, it's not the best life. But I'd do it all again, just the same. I don't think I ever had a choice, really. I was just following the inevitable path that led to the True Ending with my beloved imouto: Kirino.
