[Korean:]

자꾸 신경 쓰이게 어색해 내 모든 행동 하나하나가
괜스레 건넨 인사도 입가에 걸린 미소도 모두 Oh no, oh what should I do?

애써 무심하게 아무렇지도 않은 척하지 난 하지만
사실은 실은 실은 말야 다 티가 티가 나 I know 어떡해 나
Baby I don't really know what to do no no

How can I breathe now now now 숨 쉬는 법을 잊은 듯
I'm holding my breath 숨이 막혀 난 모두 out of my control

Oh I'm unnatural I know I'm really really really unnatural 왜
네 앞에만 서면 또 삐그덕 대 You blow my mind
맘에 안 들어
이런 내 모습 oh 내 말투
말을 안 들어 no
Really really really unnatural 왜

Yeah 그래 너는 나답지 못하게 해 love actually
기대와 불안에 가둬 날 적당히 미치게 you got me like woo
냉정함을 유지해 때로 but 안 되네 자연스런 태도 멍청한 꼴 dripping gold 뭘 더 no way
