Day6 “INSIDE OUT” Lyrics

Hangul

네 앞의 나를 볼 때, who’s that?
쿨하지 못해 구차해
매번 굳어 버린 채, mayday
속은 비상을 외쳐대

나사 빠진 듯한
말이 안되는 말
내뱉고 있는 나
한심한 걸 알지만, no (I can’t stop it)

Inside out
표정 하나 숨기지 못해
Upside down
더는 내가 아닌 듯해
Get it out
속에 묵혀 둔 말을 꺼내
Time is now
가 보자고 okay

It’s love me, love me
날 네 안에 가둬 줘
Please tell me you love me
평생 날 가져 줘

떼 쓰는 아이
같진 않을지
걱정만 한 바가지

다 알지 않을까?
말이 필요할까?
막상 하려면 딱
목에 걸려 버리지만 (I should say it)

Inside out
표정 하나 숨기지 못해
Upside down
더는 내가 아닌 듯해
Get it out
속에 묵혀 둔 말을 꺼내
Time is now
가 보자고 okay

It’s love me, love me
날 네 안에 가둬 줘
Please tell me you love me
평생 날 가져 줘

Say what I wanna say, what I gotta say
떨림을 이겨내
Do what I wanna do, what I gotta do
전해 너를 원한다고

Inside out
표정 하나 숨기지 못해
Upside down
더는 내가 아닌 듯해
Get it out
속에 묵혀 둔 말을 꺼내
Time is now
가 보자고 okay

It’s love me, love me
날 네 안에 가둬 줘
Please tell me you love me
평생 날 가져 줘
Plеase hurry, baby
갈수록 미치겠어
I’m dying, darling
빨리 날 살려 줘

Translation

When you see me in front of you, who’s that?
I’m so uncool, so pathetic
Every time I freeze, mayday
My heart screams out an emergency

I’m spitting out nonsense
I know it’s pathetic, but no (I can’t stop it)

Inside out
I can’t hide my expression
Upside down
It feels like I’m not me anymoret it out
Take out the words I’ve been holding back
Time is now
Let’s go, okay

It’s love me, love me
Lock me inside you
Please tell me you love me
Have me for life

I wonder if I sound like a child throwing a tantrum
A bundle of worries

Don’t you know everything?
Do I even need to say anything?
When I actually try to say it, it gets stuck in my throat (I should say it)

Inside out
I can’t hide my expression
Upside down
It feels like I’m not me anymoret it out
Take out the words I’ve been holding back
Time is now
Let’s go, okay

It’s love me, love me
Lock me inside you
Please tell me you love me
Have me forever

Say what I wanna say, what I gotta say
Overcome the trembling
Do what I wanna do, what I gotta do
Tell me that I want you

Inside out
I can’t hide my expression
Upside down
I don’t feel like me anymor
et it out
Take out the words I’ve been keeping inside
Time is now
Let’s go, okay

It’s love me, love me
Lock me inside you
Please tell me you love me
Have me forever
Please Hurry, baby
I’m going crazy.
I’m dying, darling.
Please save me.

Day6 “INSIDE OUT” Meaning

The title track “INSIDE OUT” captivates with its heartfelt lyrics about boldly expressing affection rather than hiding it. Serving as one of the most adventurous tracks on The DECADE, it adds emotional richness to the album.

The song portrays the nervousness and awkwardness of standing before someone you truly like, where the singer struggles to articulate their feelings, often freezing or stumbling over words. Feeling upside down and not like themselves, they yearn for the other person to notice their love, hear their heart, and promise to stay by their side. Through this mix of vulnerability, longing, and hope for closeness, “INSIDE OUT” resonates deeply with listeners who have experienced the same fragile yet powerful emotions of love.
