I'm so addicted to KIM HYUN JOONG this few days, as well as Boys Over Flowers... Haha.. Liked a song called "Because I'm Stupid". Here's the lyrics..
Because I'm Stupid - SS501
내 머리는 너무나 나빠서
너 하나밖에 난 모르고
다른 사람을 보고있는 넌
이런 내마음도 모르겠지
너의 하루에 나란 없겠지
또 추억조차 없겠지만
너만 바라만 보고있는 난
자꾸 눈물이 흐르고있어

너의 뒷모습을 보는것도 난 행복이야
아직 나의 마음을 몰라도
끝내 스치듯이 가도

니가 너무 보고싶은 날엔
너무 견디기 힘든 날에는
너를 사랑한다 입가에 맴돌아
혼자 다시 또 crying for you
혼자 다시 또 missing for you
Baby! I love you! I'm waiting for you!

너의 하루에 난 없겠지 또 기억조차 없겠지만
너만 바라만 보고있는 나
혼자 추억을 만들고 있어

내겐 사랑이란 아름다운 상처같아
너의 예쁜 미소를 보아도
함께 난 웃지도 못해

니가 너무 생각나는 날엔
가슴 시리고 슬픈 날에는
니가 보고싶다 입가에 맴돌아
혼자 다시 또 crying for you
혼자 다시 또 missing for you
Baby! I love you! I'm waiting for you!

Bye bye never say good bye
이렇게 잡지 못하지만
I need you 아무 말도 못해 I want you
바래도 다시 바래도

니가 너무 보고싶은 날엔
너무 견디기 힘든 날에는
너를 사랑한다 입가에 맴돌아
혼자 다시 또 crying for you

니가 너무 생각나는 날엔
가슴 시리고 슬픈 날에는
니가 보고싶다 입가에 맴돌아
혼자 다시 또crying for you
혼자 다시 또 missing for you
Baby! I love you! I'm waiting for you!
~END~

I bet none of you will understand right? Haha.. So I got the translated versions.. Haha..

I have the English version too..

Because I'm Stupid - SS501
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 keep coming

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 waiting 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 love you, I'm waiting for 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 love you, I'm waiting for you
~END~

I LOVE KIM HYUN JOONG MAN!!! WOOTS!!!
