I've been addicted to this song since a few weeks back...
I had this song for quite sometime already..
But only started listening to it...
This is a really nice song...
The MV is also quite meaningful...

The lyrics are as below:

Korean (Romanized)
UH...
IT'S BEEN ON MY MIND FOR A WHILE
GOT TO LET IT OUT FROM MY CHEST
BEFORE...IT'S TOO LATE

(I CAN'T LET YOU GO
YOU GOT TO LET HIM GO
I CAN'T LET YOU GO
YOU GOT TO...LISTEN)

UH...
IT'S BEEN ON MY MIND FOR A WHILE
GOT TO LET THIS OFF MY CHEST
BEFORE...IT'S TOO LATE

(I CAN'T LET YOU GO
YOU GOT TO LET HIM GO
I CAN'T LET YOU GO
YOU GOT TO...LISTEN)

I’ve been telling you everyday
I smile when I see you.
I’ve told you so many times
You’re the love of my life.
In this world full of lies, in my nervous heart
the one thing I believe in is you.
When you get nervous thinking that my feelings may change
Remember I laughed when I told you that would never happen.
A direction with no end,
my completely empty heart
The only place I can lean on is you.
And I hate that my heart sometimes wavers
Even today I get carried away by the world
and you get erased

Even if I cheat
Don’t you ever cheat, Baby
Even if I forget you
Don’t you ever forget me, Lady
If once in a while I don’t contact you
and I go out to drink
Even if I ever meet another girl’s gaze
Look only at me.

When you tell me with tears in your eyes
that you spent all night waiting up for me
you say “I think you changed.”
So many nights you ask me to tell you
that my feeling are the same as when I first met you.
Although it seems that I am miserable without you
Honestly sometimes you suffocate me
The never ending arguments
The long sighs.
Although the only place for you to lean is on me
I hate that sometimes I get sick of you
Even today I smile
and lose myself without my knowledge

Even if I cheat
Don’t you ever cheat, Baby
Even if I forget you
Don’t you ever forget me, Lady
If once in a while I don’t contact you
and I go out to drink
Even if I ever meet another girl’s gaze
Look only at me.

I know well that I’m self-centered
And I spend my days in meaningless activities
Becoming filthier, baby.
I want to leave your purity as it is,
this is my sincerity, my belief in you
Don’t leave me even in death

Even if I cheat
Don’t you ever cheat, Baby
Even if I forget you
Don’t you ever forget me, Lady
If once in a while I don’t contact you
and I go out to drink
Even if I ever meet another girl’s gaze
Look only at me.
