ENGLISH TRANSLATION
"What can I do for you?" (title) :

Always and forever, steadfast and true,
I'll stay beside you and you alone,
ever since the time I held you in my arms,
ever since the moment I felt this foresight

You, who gave me that angelic smile--
I can't ask you the reason for these tears.
You shook off my grasping hand...
and softly, over your shoulder, I started to speak

"It's all right now,"
I repeat, over and over,
to your still slightly trembling figure;
there's nothing else I can say, and yet

Always and forever, no matter when,
I'll stay here with you -- only you.
Ever since the time I held you in my arms,
ever since the moment I felt this omen...

Amid a careless conversation,
the smile you showed me was so full of joy;
I laughed in a bit of embarrassment, and,
standing there holding you without letting go, I murmured

"It's all right now..."
There's nothing else I can say, but
if those tears will vanish again,
then I'll become your clown

Always and forever, no matter when --
I'll be right there for you and you alone.
Ever since the time I held you in my arms,
ever since the moment I recognized this feeling...

I don't know whether our tears
have added up to more than our smiles, but
-I'm nearby-
That's the one thing
that I can do for you...

Always and forever, constant and steadfast,
I'll stand with you and you alone.
Ever since the time I held you in my arms,
ever since the moment I noticed this feeling

Always and forever, I alone
will never, ever let you go
Because I'll show you that I'll protect you...

since I noticed this feeling...
