Misa no Uta (From Death Note)

Be careful what you do

'Cause God is watching your every move

Hold my hand in the dark street

For if you do I know that I'll be safe

Even if I'm far away and alone

I can be sure you will find me there

This I know

You draw me close for a while, so quiet

You tell me of everything

If I forget what you say

Then you come to me and tell me again

Yes, you tell me once again

But what happens when I know it all?

Then what should I do after that?

What then?
