Lyrics Translation
I’m all in for you

I’m all in

I’m all in for you

Oh eh oh oh oh oh

I’m all in for you

May I steal your heart?

May I protect that heart?

If I fall several times and get hurt

Will you accept my surrender?

Sir yes sir, I’m saluting to your lips

I swear on your name

I’m not playing around, I put my life on the line

I’ll protect you

Oh everything about you is perfect perfect

Other girls? No thanks, no thanks

I only want you

All of me, all in, all in

If I can have you

I can do anything

Only to you, I’m all in, all in

This isn’t a lie

From now on

I’m all in for you, my body and heart

My time and money, I’m all in

I’m all in only for you

From now on

I’m all in for you

I may look a little scary girl

Don’t be scared, I’ll listen to you girl

I’m not good at expressing

So what

Jooheon

I’m all in for you

Everything about you is perfect

I need you

I only need you

Be excited, you’re my girl

Wait right there

All of me, all in, all in

If I can have you

I can do anything

Only to you, I’m all in, all in

This isn’t a lie

From now on

I’m all in for you, my body and heart

My time and money, I’m all in

I’m all in only for you

From now on

I’m all in for you

Baby you’re so beautiful

I need to have you now

I’m all in for you

I’m all in

I’m all in for you

Oh eh oh oh oh oh

I’m all in for you

Girl I’m all in

What cha sayin’

I don’t care, I want you

What I got it

I’m all in for you, all in.
