My inspiration: JYP- I Have A girl

We had no problems until I met you.

We were better lovers than anyone else in the world.
We believed that no one could come between us.
(But now, after meeting you)
The belief that I protected in my heart is defeated.
(Me without you) It's like I can't live even one day.

I have a girl but if it's like this all the time, I can't do it.
When I just look at you my heart shakes constantly
I have a girl but I'm always regretting
If you only came to my side, then, oh no, what would do? What do I do?
