I can't understand how she could leave

[노엘(1.210)]

I got home late on a Saturday night
And I knew right away something wasn't right
I knew she was gone
She took all I had, but left a hole in my heart
Should've known it'd go bad right from the start
What did I do wrong

Oh, whoa
Still, I can't understand how she could leave me this way
With nothing to say
I remember the note on the door
It said goodbye and she don't want me no more
