Before you came There weren't any problem between us The lover who is better than anyone in the world I believe strongly that no one can come between us But now that I have met you In my heart The strong belief that I have guarded have disappeared If I dont'n have you I can't live through another day I already have a man I can't always be this way But when I see you, my heart would always waver I already have a man I would always regret When you come to my side, I would be this way What should I do? What should I do? When the phone rings Even though he's by my side I wish that it was you by my side looking at me How could I miss you so much, I can't believe it However, I can't be like this I cannot make you cry Though I have made up my mind The heat that leans towards you is becoming bigger I already have a man I can't always be this way But when I see you, My heart would always waver I already have a man I would always regret When you come to my side, I would be this way What should I do? What should I do? My heart is really painful I can't breathe easy I can't see the road in front of us I don't know where I would go I already have Jo Kwon I can't always be this way But when I see you, My heart would always waver I already have Jo Kwon I would always regret When you come to my side, I would be this way What should I do? What should I do? What should I do? What should I do? What should I do? What should I do?
