Where are you at?
Where have you been?
There's no answer to the question 

Where are you headed?
What did you mean?
Chasing after you 

A bird, a butterfly and my red scarf
Don't make a mess of memories 
Just let me heal your scars 

The wall, the all forgotten war
Time never stops 
We're getting older second by second by second 

Why oh why? 
Why oh why?
Don't you want to stay with me?
Why oh why? 
Why oh why?
Are you giving up on me?
I'll be waiting, waiting for you
Let me hold you under the tree
Under the tree
I'll protect you
