#IOI - 웃으며 안녕 (Smilingly Say Goodbye) lyrics Eng trans: Now, even if I look back, I’ll only see an empty space. Only the scent about to bloom wets my nose. Even if I just pass by, I keep lingering in that spot. Like a lingering regret I couldn't let go of. Now, everything will change little by little. It will hurt, it will be hard, but. For you. Even if my heart aches, because we know each other so well. Goodbye with a smile, goodbye with a smile. Because it will hurt more as much as I loved. Because it will hurt so much. Goodbye to each other with a smile. Even if we are far apart, I'm with you. I will take a place in your heart. I'm with you. I'm with you baby, I'm with you. So you won't fade from my memory, I'm with you. In front of the ticking clock, I’ll probably just chase after time blankly. Time, unaware of my heart, flows by quickly. Now, everything will change little by little. It will hurt, it will be hard, but. For you. Even if my heart aches, because we know each other so well. Goodbye with a smile, goodbye with a smile. Because it will hurt more as much as I loved. Because it will hurt so much. Goodbye to each other with a smile. Love, you and I Fading away into the memories we made together Can't I take all your pain with me? I'm truly sorry. Goodbye now. Even though it hurts, we know each other so well. Goodbye with a smile, goodbye with a smile. Because it will hurt more as much as I loved you. It will hurt so much. Goodbye with a smile. Goodbye. The meaning of goodbye has changed now. I was happy that my precious love was you. Thank you for loving me. #아이오아이 #IOI #IOI_LOOP #웃으며안녕
