English:

My Heart is like girl’s emotion
My heart was pounding oh baby
Is full of you, boy
as sweet as pickle apple juice, oh oh oh baby

My mom told me I am pretty
why why why why why hey hey
In this my heart and mind
out out up&down

here we go now a compass direction you
find last treasure
I will give you I refuse to accept your refusal
I am only you

huh I’m very surprised
um I still do not know
You are on your side

I hate you, my bursting heart that you keep squeezing and unfolding
I hate you, my hands that you playfully hold and let go, it’s an up and down
Roller coaster Roller coaster
Roller coaster Roller coaster
Ah ah you are
Roller coaster

I dreamt of you but it’s so unfortunate that I woke in the morning
I kick the blanket, I kick the blanket yap
I daydream of you but it’s so unfortunate that I get conscious
I kick the blanket, I kick the blanket ya

1 plus 1 is not 2
1 plus 1 is you and me who glued to each other
1 plus 1 is not kwiyomi (cute)
1 plus 1 is the perfect of you and me

The thing I hope is only one
It’s your heart, heart heart heart
Don’t you run away
I will tagged firmly to you tteng tteng tteng

Come here and welcome me
If I see a sign board which is you, I will run to it
In my dream I hug you tight
If I wake up then I will spit
My head that I squeezed tight
My throat that feels suffocated
You drove me crazy
but somehow I need you

I hate you, my bursting heart that you keep squeezing and unfolding
I hate you, my hands that you playfully hold and let go, it’s an up and down
Roller coaster Roller coaster
Roller coaster Roller coaster
Ah ah you are
Roller coaster

In a dark night I will be your starlight
When you lost track I will shine your way
Yeah im going up&down
I don’t know what to do
I’m searching for you boy
Stop pushing and pulling me

I hate you, my bursting heart that you keep squeezing and unfolding
I hate you, my hands that you playfully hold and let go, it’s an up and down
Roller coaster Roller coaster
Roller coaster Roller coaster
Ah ah you are
Roller coaster

I dreamt of you but it’s so unfortunate that I woke in the morning
I kick the blanket, I kick the blanket yap
I daydream of you but it’s so unfortunate that I get conscious
I kick the blanket, I kick the blanket yap

Korean:

소녀감성 차올라 내맘이
두근두근 거리잖아 oh baby
소년미 가득 너에게
맛있는 사과주스 사주고파 oh oh oh baby

울 엄만 내가 젤 예쁘다던데 넌
why why why why why hey hey
머리로 내게만 이런 마음은 또
out out up&down

here we go now 나침반 너를 향했지
마지 보물찾기
중이지 나를 선물할게 거절은 거절 받아줬음 해 난 너뿐이지

huh 많이 놀라지
um 있어 가만히에라 모르겠다
네가 다기가 쪽쪽쪽

미워요 피어나는 내 맘을
쥐었다 폈다 쥐었다 폈다
미워요 안절부절 내 손을
쥐었다 폈다 올라갔다 내려가는
롤러코스터 롤러코스터
롤러코스터 롤러코스터
ah ah ah 너는
롤러코스터

널 꿈꾸다
아침이 찾아오면 아쉬워서
이불킥 입불킥 얍
널 생각하다
정신을 차려보면 아쉬워서
이불킥 이불킥 얍

1 더하기 1은 2가 아니야
1 더하기 1은 깍지 낀 너와 나
1 더하기 1은 귀요미가 아냐
1 더하기 1은 완벽한 너와 나

내가 바라는 건 오직 하나
너의 마음 맘 맘 맘 맘
도망가지마요 내가 술래
얼음 땡 땡 땡 땡

어서와 나를 반겨
너란 표지판을 보고 달려
꿈에 너란 품에 꼭 안겨
깨면 앞에서 침을 사켜
복잡해지는 머리 속
꽉 막혀지는 나의 목
you drove me crazy
but somehow I need you

미워요 피어나는 내 맘을
쥐었다 폈다 쥐었다 폈다
미워요 안절부절 내 손을
쥐었다 폈다 올라갔다 내려가는
롤러코스터 롤러코스터
롤러코스터 롤러코스터
ah ah ah 너는
rolleokoseuteo

어두운 밤 달빛이 될게
길을 잃어도 비춰줄게
yeah I’m going up&down
I don’t know what to do
I’m searching for you boy
그만 좀 들었다 놔

미워요 피어나는 내 맘을
쥐었다 폈다 쥐었다 폈다
미워요 안절부절 내 손을
쥐었다 폈다 올라갔다 내려가는
롤러코스터 롤러코스터
롤러코스터 롤러코스터
ah ah ah 너는
롤러코스터
