시골 길 여름 바람에 반딧불이 떴어

너와 걷던 그 길—반딧불이 빛이 날 감싸

[whisper/echo] “기억나?”

손끝에 스치듯—와르르 번지고 사라져

작은 불빛 같던 우리도 그랬지

반딧불아, 반짝여 줘—한 번만 더(한 번만 더)

Fireflies, stay, stay—stay tonight

불빛처럼 와서 나를 비추고

다시 멀어져—사라진 너(사라진 너)

반딧불아, 반짝여 줘—내 맘에 더(내 맘에 더)

Fireflies, stay, stay—don’t fade tonight

네가 웃던 그 벤치—빈자리만 남아

[whisper] “여기 있어?”

짧게 켰다 꺼진—카톡의 울림처럼

우린 신호를 놓친 채 밤이 깊어졌지

[whisper] “돌아올래?”

반딧불아, 반짝여 줘—한 번만 더(한 번만 더)

Fireflies, stay, stay—stay tonight

불빛처럼 와서 나를 비추고

다시 멀어져—사라진 너(사라진 너)

반딧불아, 반짝여 줘—내 맘에 더(내 맘에 더)

Fireflies, stay, stay—don’t fade tonight

내 손바닥 위—한 점의 빛이 떨려

부르면 멀어져—멀수록 더 선명해

“우린 잠깐이었대도, 영원처럼 뜨거웠어”

꺼지지 않게—내 가슴에 너를 남겨

반딧불아, 반짝여 줘—마지막도(마지막도)

Fireflies, stay, stay—stay tonight

불빛처럼 와서 나를 감싸고

또 멀어져도—기억은 빛나(빛나, 빛나)

반딧불아, 반짝여 줘—내 밤에 더(내 밤에 더)

Fireflies, stay—(stay) stay—(stay) don’t fade tonight
