기억에 남겨둔다면 행복할 수 있죠 사각사각 진한 연필로 내 이름을 쓰고 있나요 사르르 녹아버릴 듯 날 바라보던 그 눈빛을 떠올려요 우리끼리 미리 허락 받지도 않은 채 말랑거리는 사랑을 해도 되는 건지 하지만 뭐 어때 마법처럼 날 것 같은 기분 숨길 수 없어 Oh Day by day Day by day 내 마음도 네 맘처럼 사랑으로 채워 넣을게 크림처럼 포근하게 서로를 위해 바라봐요 항상 좋은 일만 생각해요 Day by day Day by day 내 마음도 네 맘처럼 사랑으로 채워 넣을게 크림처럼 포근하게 서로를 위해 바라봐요 항상 좋은 일만 생각해요 [English translation:] When I open my eyes, there's sweet sunshine With the fresh aroma of fruits all around With a full cup of mocha latte, I sit on this small terrace And when I think of you I start to smile unknowingly It feels like only good things are going to happen My day's excitement That no one else can bother I can feel it We haven't asked each other if this is possible If we can love like this But, but who cares, like magic I can't hide this feeling like I'm about to fly Oh, day by day, day by day, My heart, like your heart too I'll fill it with love, Like a soft cream, let's look upon each other Please think only of the good things Even if at times, some things May hurt my heart If I just think of those wonderful memories of you I can be happy With a dark square pencil Are you writing my name? Your burning eyes that seem like it'll melt me Comes to my mind We haven't asked each other if this is possible If we can love like this But, but who cares, like magic I can't hide this feeling like I'm about to fly Oh, day by day, day by day, My heart, like your heart too I'll fill it with love, Like a soft cream, let's look upon each other Please think only of the good things Oh, day by day, day by day, My heart, like your heart too I'll fill it with love, Like a soft cream, let's look upon each other Please think only of the good things
