Why?

YUI

I know you're hiding something
Every time I look at you, you look like you're going to 
fall apart

You must have a heart, right?
All you've done lately is laugh

Sometimes I've been overwhelmed by sadness
Though I thought I trusted you

Why do people have words?
They make our hearts harder to see

At the moment I'm like something a traveller finds as 
they wander aimlessly
I can't even chase you too far

You must have mistaken me for someone else
In that case, say it more strongly

Sometimes I've been overwhelmed by sadness
Though I thought I trusted you

Why am I doubting you?
You mean more to me than anyone else

I'm scared, and sometimes things get tough
But I'll trust you from now until forever

Why do people have words?
They make our hearts harder to see
