Translation (by webtoonlive)

My heart is like an empty room 
One looks for it
The only thing I can do is to look
Out into the dark sky
And each time I do
I think of us  [bad word] back
And get me out of here
There's nothing I can do
But if that's [bad word] back and embrace me
Let me breath
Embrace me
Let me breath
Please be beside me
And get me out of here
