I'm Serious (장난 아닌데)

I don't know why why why every night
Just staring at the ceiling
Oh my, is it because of you
That I'm burning up

Even if I give you hints to understand
You don't understand at all
Why don't you know that (oh no)
I really only have you

I'm serious
It's written in my eyes that I like you right now
Why don't you feel it?
It's already showing on my face

Are you going to keep smiling vaguely and pass it off?
Like that, like that, are you going to keep doing this all the time?
My growing heart, please do something about it
(I can't stop loving you)

Should I give up on this feeling of mine
Even after thinking about it for several sleepless nights
No, no, because of you
My gaze can't go elsewhere

Even if I try to express my feelings to understand yours
You just brush it off like a joke
Why don't you know that (you know)
I'm only looking at you

I'm serious
It's written in my eyes that I like you right now
Why don't you feel it?
It's already showing on my face

Are you going to keep smiling vaguely and pass it off?
Like that, like that, are you going to keep doing this all the time?
My growing heart, please do something about it
(I can't stop loving you)

In the end, I keep hearing useless words
(Just hearing words)
And I smile as I let you go
Why am I like this oh

I'm serious
It's written in my eyes that I like you right now
Why don't you feel it?
It's already showing on my face

Are you going to keep smiling vaguely and pass it off?
Like that, like that, are you going to keep doing this all the time?
My growing heart, please do something about it
(I can't stop loving you)

I can’t stop loving you
I can’t stop loving you
