Many authors have explored the night Kenshin said goodbye to Kaoru, perhaps the most poignant and romantic scene in the entire RK series.  I believe Linda Ronstadt's song is the perfect expression for what might have been going on in Kaoru's mind right after the farewell.  It's a short song, sad and beautiful.

Disclaimer: Rurouni Kenshin is not mine, and neither is the song, "Long, Long Time."  Noboru Watsuki and Linda Ronstadt are their creators, respectively.  I submit this only in admiration of both their talents, without benefit to myself.

Long Long Time

You turned and walked away, just like that.  And I couldn't follow…

Love will abide
Take things in stride
Sounds like good advice
But there's no one at my side

If I stay like this forever, they'll all start to worry about me.  Yahiko…he was in here already asking about you.  I think he's worried.  I wanted to say something to him, but the words wouldn't come out.  Just as they wouldn't come out after you…I think he's gone to find help.  I can't stay here forever, but I…I just can't…get up, Kaoru, get up!

And time washes clean
Love's wounds unseen
That's what someone told me
But I don't know what it means

Kenshin?  Kenshin?  I can only make it this far.  This is where you fought and became the Battousai.  It scared me Kenshin, because I thought I would really lose you.  But it didn't matter, did it?  You've gone away anyway, gone to fight because you think you have to.  Why couldn't I have gone with you?

Cause I've done everything I know
To try and make you mine
And I think I'm gonna love you
For a long, long time

 Remember the first time we met?  You had me fooled, I admit.  But then, that was the point.  You saved my life for the first time…even then, that short moment, I remember what it was like to be in your arms.  And that time on the riverbank, when that madman took me away from you…

Caught in my fears
Blinking back the tears
I can't say you hurt me
When you never let me near

Was it my tears that stopped you, stopped you from killing him?  I remembered what you said, what it meant for you to go back on what you have been doing as a rurouni who doesn't kill.  I couldn't let you sacrifice that, not for me.  I understood what it would do to you, and I couldn't be alone again.  You came back to me, but you never…afterward…

And I never drew
One response from you
All the while you fell
Over girls you never knew

I wanted to know about your past.  You were hurting because of it, and I wanted to understand, to give you someone to talk to.  But you never opened up about it.  And try as I might, You would just look at me with that smile that never reached your eyes, that painful smile…it made me so angry that you thought you could stay silent.  And your past caught up to you…I tried to keep you from meeting it.  But you slipped from my hands, pulled away from me…

And I've done everything I know
To try and make you mine
And I think it's gonna hurt me
For a long, long time

I didn't care what that wolf said.  I wasn't going to get out of the way for him.  You had protected me too many times; it was my turn to be your shield.  I didn't care that you were changing right in front of me, going back…

Wait for the day, you go away
Knowing that you warned me
Of the price I'd have to pay

"I am a wanderer and I don't know when I might leave again."  You warned me then, didn't you?  I didn't listen, I couldn't listen to what you said.  Even when you swore to kill him, even when you were ready to throw away everything to kill him, I thought I could reach you one more time…

And life's full of loss
Who knows the cost
Living in the memory
Of the love that never was

…but it wasn't enough.

Cause I've done everything I know
To try and change your mind
And I think I'm gonna miss you
For a long, long time

It was such a beautiful night.  Odd that a night so beautiful would follow a day so terrible.  But that night was terrible to, in the firefly light as I pleaded with you…and you didn't answer.  I knew then. And you put your arms around me and held me close.  Do you know how often I have wished for, dreamed for, prayed for you to do that?  Why did it have to be that night, that instant that I knew…that I knew I would lose you forever?  Why is it that I can't stop crying?  Why can't I stop my heart from hurting?


And I've done everything I know
To try and make you mine
And I think I'm gonna love you
For a long, long time
