Because I'm Stupid by SS501
(English Translation)

I’m really, very foolish
I know of no one other than you
you’re looking at someone else
yet you have no idea of my feelings like this

I won’t be in your days
I won’t be in the memories either, however
only you, I looked only at you
and the tears [bad word] 

As i watch you walking past, I’m still happy
even yet you still don’t know my heart
I should stop this and go

I really want to see the day
I’m withstanding the pain each day
“I love you” is playing on my lips
Alone once again, crying for you
alone once again, missing for you
Baby, I love you, I’m wiating for you

I won’t be in your days
I won’t be remembered either, however
only you, I looked only at you
I’m making memories alone

Loving you is like having a beautiful wound
I look at your pretty smile also
but I cannot laugh with you

I’m thinking about you so much everyday
my heart is hurting in all these sad days
‘I want to see you’ is playing on my lips
alone once again, crying for you
alone once again, missing for you
Baby, i’m waiting for you, I love you

bye bye, never say goodbye
even though I cannot hold you like this
I need you, I cannot say anything more, I want you
I keep on hoping too, I’ll keep hoping….

I really want to see the day
I’m withstanding the pain each day
“I love you” is playing on my lips
Alone once again, crying for you

I’m thinking about you so much everyday
my heart is hurting in all these sad days
‘I want to see you’ is playing on my lips
alone once again, crying for you
alone once again, missing for you
Baby, i’m waiting for you, I love you
