Once upon a time 
A few mistakes ago
You were in my sight
I found you 
I found you 
I found you on YouTube

I guess you didn't care
And I guess I liked that
And when I fell hard
You didn't show
there was no interview, special stage or comeback

And you didn't show 
When I see Daehyun
I realize the blame is on me

Cause I knew you where trouble when you debuted
So shame on Lee So Man
Flew me to places I'd never been
Made me take Korean lessons
I knew you were trouble when you showed your abs
So shame on your fitness-trainer
Flew me to places I'd never been
Now I am starting watching Daehyuns vids

Oh, oh, trouble, trouble, trouble
Oh, oh, trouble, trouble, trouble

No more vids
No more winks
Never showing your chocolate abs again
You're reason why I think all the boys in my class are ugly

And I heard you plan your comeback
From rumours on tumblr
Someone you don't know exists
Is all I'll ever be
And now I see, now I see, now I see
You never did a comeback
When I see Daehyun
I realize the joke is on me

I knew you where trouble when you danced
So shame on Music-Bank
Flew me to places I'd never been
Made me read fanfics
I knew you were trouble when you your lips
So shame on your thick-fat-marchmallow-like lips
Flew me to places I'd never been
Now I am starting reading Daehyun fics

Oh, oh, trouble, trouble, trouble
Oh, oh, trouble, trouble, trouble

When your sadest fear comes creeping in
That you'll never be a better dancer than Teamin 
Yeah (you're of course a better dancer than Taemin)

I knew you where trouble when you pouted
So shame on your cute expression
Flew me to places I'd never been
Made me want to try kimichi
I knew you were trouble when you smirked
So shame on your iness
Flew me to places I'd never been
Now I am starting seeing only Daehyun

I knew you wer trouble when you showed on YouTube
But I never regretted it
I knew you were trouble
I can't get you out of my mind!

hahahahhahah who knows the original song lyrics ????
