Here are the lyrics. If you guys want to follow along ^.^

Day by Day (Originally Haru Haru by Big Bang)

(Verse 1)

Guess I gotta be stronger and laugh now

Better to move on and finally laugh now

Still this pain still echoes inside me

Can't shake off this feeling that I'm fighting

All these memories keep coming back to me

Guess I gotta have to endure it some more and (Say goodbye)

Guessed I wouldn't be able to go on living without you

But to my surprise I'm doing pretty good without you

Even though I sometimes catch myself crying, I miss you

I'm still expecting that you'll come back to me

Now baby, are you happy without me?

Are you feeling a little bit lonely?

Are you crying out that you love me?

Or did you already forget me?

And I'm so lost, did you find someone new?

Does she treat you better than I ever could, boy?

I hope so, now I'm trying to erase every trace of you

But I just can't let go

(Chorus)

Don't look back just leave me with all the shame

Forget me and the times I caused you such pain

But all the love I gave, I gave it without regret

Hope you understand my feelings were true

Remember all the good times that we had

I wish that I could take back all the bad

And have you back in my arms once again

Day by day, the hurt will slowly fade away

(Verse 2)

Sometimes I wish I still could be able to see you

Even though we both know that it has become impossible

To hear your voice is something that I'll always long for

But still I'll fight and try to go on letting you go

(I'm suffering) Ever since I caused you such pain

(I'm suffering) Even though I'm saying I'm okay

And my heart keeps breaking now that you're away

And our distance keeps growing every single day

So promise me, that you'll go and find happiness

And I'll keep smiling and endure the sadness

Just let me be the only one who's suffering

Boy, I'm not sorry it had to end this way

(Chorus)

Don't look back just leave me with all the shame

Forget me and the times I caused you such pain

But all the love I gave, I gave it without regret

Hope you understand my feelings were true

Remember all the good times that we had

I wish that I could take back all the bad

And have you back in my arms once again

Day by day, the hurt will slowly fade away

(Bridge)

Hope your heart's relieved after leaving me

(Never thought these words could hurt so much)

Lets those tears become a memory

(As day by day passes, yeah)

Maybe if we wouldn't have met this pain wouldn't have come

But as for me, I'll have to go on living with regret

The one I've lived with since the day you left me

Now I'm left saying...

(Chorus)

Don't look back just leave me with all the shame

Forget me and the times I caused you such pain

But all the love I gave, I gave it without regret

Hope you understand my feelings were true

Remember all the good times that we had

I wish that I could take back all the bad

And have you back in my arms once again

Day by day, the hurt will slowly fade away
