My heart won’t listen to me
I keep fallin for you
I keep acting not like me
I keep fallin for you

If you avoid him, you lose, look at him straight up
I keep telling myself
But when I see you, not moving at all
I turn my head

Following, my eyes are following you
In the end, I’m the one who loses, why
Be careful because I don’t know where this will take me

I call you Iron boy
I call you Iron boy
I call you Iron boy
Your indifferent face, your transparent mood

What do I do? Of course, you’re not easy
Be careful because I don’t know where this will take me
Whoa, I’m fallin’ at the blink of an eye

It’s not a big deal, just keep it simple
But if it’s not you, it’s always easy to say
I’m serious, this is a big deal to me
Poker face, I can’t do it, I’m too honest
I wanna melt you, I’m gonna be a fire, I’m going straight to you

Getting to know you slowly
In the end, it’s me who approaches you, why
Be careful because I don’t know where this will take me

I call you Iron boy
I call you Iron boy
I call you Iron boy
Your indifferent face, your transparent mood

What do I do? Of course, you’re not easy
Be careful because I don’t know where this will take me
Whoa, I’m fallin’ at the blink of an eye

I call you Iron boy
I call you Iron boy
I call you Iron boy

Of course, I know you’re not easy
But you should be nervous because I won’t lose that easily
I’m sure this feeling will reach you
And shake you up
