NCT DREAM - Sorry, Heart

You'll always be by my side
Did my greed make you tired?
Sifting through a fine sieve
I'm just looking for the right words
The words of complex excuses

I know that
All I can do is
I'm sorry, that's all I can say (That's all I can say)

Tell me why I (Tell me why I)
Let you down (Let you down)
Any chance I get I'm (Yеah)
Breaking down (Breaking down, breaking down, yеah)
I know it's my fault (I know), but why is it so hard?
To tell you that I'm sorry, heart
