AtHeart “Butterfly Doors” Lyrics

Hangul

(Aim your heart)
Butterfly doors open up for me
다른 세상 속 내가 된 듯이
이상하고 뭔가 낯선 이 느낌
날 끌어당긴 넌 날 보며 웃었지

발견해 버린 호기심 속 너의 눈빛
마치 내 행성에 불시착한 외계인
맘이 막 자꾸만 몰래 뛰어댔지
순간 온 세상이 흔들리는 듯했지
What’s wrong? (What’s wrong?)
고장이 난 심장이 아파 all day
이러지 마 장난은 그만 okay
두 눈앞엔 별이 맴돌아 no way (No way)
비밀스레 너는 또 웃네, oh, wait

별안간 파고든 설레임 (설레임)
소란하게 흔들린 내 중심 (Ah)
장난스레 넌 나를 흔들지

Pull me in, I’m fallin’ for you
어느새 aim your heart
중심이 널 향하고
내 맘이 툭 기울지
Ooh, I’m fallin’ for you
세상을 뒤집는 중
아껴 둔 온 맘이 자꾸
네게로 툭 기울지 (Hey, you)

너를 따라 피어나는 모든 emotion
놀려대듯 시선을 홀린 your motion
빈틈없이 빠져버린 둘만의 tension
Tension (Tension)
Tension, yeah, yeah, yeah

또다시 파고든 설레임 (설레임)
요란하게 흔들린 내 중심 (Ah)
장난스레 넌 나를 흔들지

Pull me in, I’m fallin’ for you
어느새 aim your heart
중심이 널 향하고
내 맘이 툭 기울지
Ooh, I’m fallin’ for you
세상을 뒤집는 중
아껴 둔 온 맘이 자꾸
네게로 툭 기울지 (Hey, you)

(Ooh, ah, ooh)
(Ah, ooh, ah, ooh)
맘의 거릴 넘어 네게 기울어갔지 (Ah, ooh)
맘의 거릴 넘어 (Ah, ooh)
맘의 거릴 넘어 (Ah, ooh)
맘의 거릴 넘어 네게 기울어갔지 (Ah, ooh)

Butterfly doors open up for me (Ah, ooh)
어느 꿈결 속 내가 된 듯이 (Ah, ooh)
신기하고 설레이는 이 느낌 (Ah, ooh)
날 끌어당긴 너를 보며 웃었지 got you

Translation

(Aim your heart)
Butterfly doors open up for me
As if I’ve become myself in a different world
This strange and somewhat unfamiliar feeling
You, who pulled me in, smiled while looking at me

Your eyes filled with a curiosity I just discovered
Like an alien who crash-landed on my planet
My heart kept beating fast in secret
It felt like the whole world was shaking for a moment

What’s wrong?
My broken heart hurts all day
Don’t be like this, stop teasing okay
Stars are spinning before my eyes no way
Secretly, you smile again oh wait!

A sudden flutter that pierced through me
My center that was shaken up noisily
Playfully, you shake me up

Pull me in, I’m fallin’ for you
Before I know it, aim your heart
My center is facing toward you
And my heart suddenly tips over

Ooh I’m fallin’ for you
In the middle of turning the world upside down
All the heart I’ve saved up keeps
Suddenly tipping toward you
Hey you

Every emotion that blooms following you
Your motion that charms my gaze as if teasing me
The tension between just us two that I’ve fallen into completely
Tension tension tension yeah yeah yeah

Once again, the flutter that pierced through me
My center that was shaken up loudly
Playfully, you shake me up

Pull me in, I’m fallin’ for you
Before I know it, aim your heart
My center is facing toward you
And my heart suddenly tips over

Ooh I’m fallin’ for you
In the middle of turning the world upside down
All the heart I’ve saved up keeps
Suddenly tipping toward you
Hey you

(Ooohhh)
Crossing the distance of my heart, I tipped toward you
Crossing the distance of my heart
Crossing the distance of my heart
Crossing the distance of my heart, I tipped toward you

Butterfly doors open up for me
As if I’ve become myself inside a dream
This marvelous and fluttering feeling
I smiled while looking at you, who pulled me in
Got you

AtHeart “Butterfly Doors” Meaning

AtHeart’s “Butterfly Doors” represents a bold step into a new chapter for the group, symbolizing growth, ambition, and emotional exploration. Following the confident tone established in their earlier track “Shut Up,” the song expands that certainty into a deeper and more expressive world. The lyrics reflect the idea of opening doors to new experiences, embracing change, and moving forward with confidence.

The title itself carries a powerful visual metaphor. “Butterfly doors,” like the upward-opening doors of a luxury supercar, symbolize breaking boundaries and rising to a higher level. This imagery reflects the group’s determination to elevate their music and presence while stepping into a broader global stage.

The song also hints at the concept of the “butterfly effect,” suggesting that small actions can create a larger ripple across the music industry. Through their vibrant “HeartTeen” charm and high-teen musical style, AtHeart aims to make a meaningful impact and connect with listeners worldwide. With its uplifting message and evolving sound, “Butterfly Doors” highlights the group’s ambition to grow and spread their wings as a rising fifth-generation act.
