[Korean:]

난 알고 싶어 널
매일 아침 시작과 끝에
내가 너의 하루에
당연한 습관이길 바래 oh

조금 쳐진 눈
아쉬울 때면 짓는 니 표정
전부 궁금한데

Oh this is that love
Sure it's that love
너라면 모든 게 난 좋아
Oh this is that love
Falling for you
순간의 감정만은 아니야
Oh this is that love
I'm sure it's that love
Oh this is that love
I'm falling for you

조금은 불안해 가끔
어지러운 세상에 넌
내 손 놓치진 않을까
그럴 때면 내게 와준
너의 손 꼭 붙잡고서
세상 어디라도 함께 할게

빨개지는 볼
따스한 손길 환한 웃음이
나도 궁금한데

Oh this is that love
Sure it's that love
너라면 모든 게 난 좋아
Oh this is that love
Falling for you
순간의 감정만은 아니야
Oh this is that love

오늘은 내가 먼저 말할래
정말 널 많이 사랑해
너무 소중해서 늘 감사해
I will be better with you

Oh this is that love
Sure it's that love
너라면 모든 게 난 좋아
Oh this is that love
Falling for you
순간의 감정만은 아니야
Oh this is that love
I'm sure it's that love
Oh this is that love
I'm falling for you
