Lyrics:

You already understand, and that’s enough
I really have a certain sorrow
That’s connected to my tears and won’t let them full
My eyes can only follow you as you leave
My biggest regret
Is your biggest regret, and it has something to do with me
There’s no point, it’s already perfect
There’s no need for misunderstandings, the telling of the story isn’t finished

What else can be done
Me and sadness, are an extravagant duo
I miss when you were that close to me
But in the end, you just can’t
Come along with me, can’t go back, far away
Originally I was so happy
But I just couldn’t admit it
Inside of my doubts, in the time of the world
You had given me an answer

My biggest regret
Is your biggest regret, and it has something to do with me
There’s no point, it’s already perfect
There’s no need for misunderstandings, the telling of the story isn’t finished
What else can be done
Me and sadness, are an extravagant duo

I miss when you were that close to me
But in the end, you just can’t
Come along with me, can’t go back, far away
Originally I was so happy
But I just couldn’t admit it
Inside of my doubts, in the time of the world
You had given me an answer

Me reaching happiness
Is seeing you happy
There was a time we could make time go slow with our own hands
But, we didn’t wait for us
