First kiss 그땐 풋풋했었지
열일곱 되고 꽃이 피던 어느 날
첫 사랑에 허우적대던 내가
사탕 같은 사고를 치고만 거야

So sweet 달콤한 달빛아래
So sweet 딩동 내게 벨이 울렸고
So hot 두 볼엔 불이 난 채
I'm falling I'm falling

Beautiful first kiss 눈부신 First kiss
너란 세상에 난 물이 들고
사랑에 빠진 달콤한 떨림 Oh
처음 느낀 Fantasy world

그땐 너무 떨렸어 Oh first love
첫 키스에 설레었던 나
그땐 너무 어렸어 Oh first love
첫 키스에 첫 사랑이던 너
잘 있을까

First love 그땐 순수했었지
너와 했던 모든게 처음이었어

너와 나의 비밀스런 그 밤
가끔 난 그 밤을 들춰 보곤 해

So sweet 처음 맛본 그 떨림에
So sweet 순간 꼼짝 얼어버렸고
So shy 발끝은 막 들린채
I'm falling I'm falling

Beautiful first kiss 눈부신First kiss
너란 세상에 난 물이들고
사랑에 빠진 달콤한 떨림Oh
처음 느낀Fantasy world

그땐 너무 떨렸어Oh first love
첫 키스에 설레었던 나
그땐 너무 어렸어Oh first love
첫 키스에 첫 사랑이던 너
잘 있을까

눈만 맞춰도 두근두근 떨리던 나
참 행복했었어
손만 잡고도 새빨갛게 부풀던
그 옛날의 내가 그리워

Ah ah
Beautiful first kiss 눈부신First kiss
너란 세상에 난 물이들고 (물이들고)
사랑에 빠진 달콤한 떨림 Oh
처음 느낀 Fantasy world

그땐 너무 떨렸어 Oh first love
첫 키스에 설레었던 나
그땐 너무 어렸어 Oh first love
첫 키스에 첫 사랑이던 너
잘 있을까

G.NA

G.NA was born as Gina Jane Choi in Edmonton, Alberta, Canada on September 13, 1987, to South Korean immigrants. She moved to her parents' birth country to begin a career in the music industry and was originally slated to be a member of a girl group called Five Girls under Good Entertainment in 2007. However, after the company had financial troubles and went into bankruptcy, and the members left and joined other companies after a year, G.NA followed suit and joined CUBE ENTERTAINMENT.

Despite debuting as a feature on the track “애인이 생기면 하고 싶은 (Things I Want to Do When I Have a Lover)” featuring Bi Rain on July 5, 2010, G.NA really hit it off with her songs “Black & White and “꺼져 줄게 잘 살아 (I’ll Back Off So You Can Live Better) featuring Junhyung“.

Choi would continue to release songs and albums under CUBE ENTERTAINMENT and even made a collaborative track with Aaron Yan for the track “Half (½)”, which was the original soundtrack for his drama 愛上兩個我 (Fall In Love With Me) (2014) until she left the company and the entertainment industry as a whole in 2016 due to a prostitution scandal.
