Secret

Great Translation :)

Only piano is left here and it spent a whole day talking with me. The cello that's been sleeping is silent and worn. I think you have made it very clear (for me) to understand. I am aware
and know too that there is no reluctance in you

You said that you will feel completely broken-heart too, but i don't believe it. Though i used to hold your hands and you spent time
with me, it was all history.

I really hope that he really loves you more than i ( still) do, only then can i force myself to leave you

Reff:

You want a farewell, but i simply do not want to end this relationship. Why do you expect me to be smiling and pretend like nothing
has happened? I don't have a talent like this, embracing you and accepting him. Don't worry too much about me, I'll survive and live well.

You are very far away from me now, and i will also slowly walk away (from your life). Why do i even let you to choose how and when we break up ?
I really have no talent , I can't soothe (be in silence) that quick. I will learn to give you up and that is because I love you so.
