[Korean:]

갤럭시 너 혹시 나와 같이 걸어가 볼래
반짝이는 은하 너머 손잡고
나와 같이 걸어가 볼래
누가 살고 있나 아무도 몰라
그 너머 뭐 있는지 누구도 몰라
다만 분명히 화려한 무지개
너머 내 꿈 둥 둥 떠다닐 거예요

Tap the galaxy oh
Dab the melody ya

할까 말까 고민 끝에 한여름날 쉬다 간
여우비 소리에 묻혀
말하지 못한 내 고백이
저 하늘 희미하게 반짝이고 있는
은하수로 흘러갔을까

갤럭시 너 혹시 나와 같이 날아가 볼래
반짝이는 팅커벨의 가루가
너와 나를 띄워 줄 거야

누가 숨어 우릴 볼지도 몰라
날 위한 축제가 있을지도 몰라
다만 분명히 영롱한 물안개
너머 내 꿈 둥 둥 떠다닐 거예요

Tap the galaxy oh
Dap the melody ya

할까 말까 고민 끝에 한겨울밤 몰래 간
도둑눈에 숨이 멎어
도망가 버린 고백 말이
저 하늘 희미하게 반짝이고 있는
은하수로 흘러갔을까

갤럭시 너 혹시 나와 같이 걸어가 볼래
반짝이는 은하 너머 손잡고
나와 같이 걸어가 볼래
갤럭시 너 혹시 나와 같이 날아가 볼래
반짝이는 팅커벨의 가루가
너와 나를 띄워 줄 거야

[English translation:]

Galaxy, wanna take a walk with me?
Wanna cross the twinkling Milky Way and hold hands
And walk with me?
No one knows who lives there
No one knows what's out there
But my dreams will definitely be
Floating there past the flashy rainbow

Tap the galaxy oh
Dab the melody ya

Should I do it or not? At the end of deep thought
Because of the sound of the midsummer rain
I couldn't confess to you
Did it float off to the Milky Way
That is faintly shining in the sky?

Galaxy, wanna take a walk with me?
The twinkling Tinkerbell pixie dust
Will make me float

Someone might hide and see us
There might be a party for me
But my dreams will definitely be
Floating there past the hazy fog

Tap the galaxy oh
Dap the melody ya

Should I do it or not? After thinking about it
After my breath stopped from your eyes
The midwinter confession ran away
Did it float off to the Milky Way
That is faintly shining in the sky?

Galaxy, wanna take a walk with me?
Wanna cross the twinkling Milky Way and hold hands
And walk with me?
Galaxy, wanna take a walk with me?
The twinkling Tinkerbell pixie dust
Will make me float
