"After we broke up, you look better, pretty woman
Yeah yeah yeah yeah
Annoyingly, you still look good, pretty woman
Oh pretty woman
Don’t wanna be fool, wanna be cool
Wanna be loved, same love as you
I know it’s over
Don’t wanna be fool, wanna be cool
Wanna be loved, same love as you
Baby I want it"
 

After Hoseok broke up with his girlfriend, he was heartbroken. He lost her. She wasn't ever coming back, and he knew it.

And it was all his fault. 

Maybe if he hadn't gotten jealous, maybe if he hadn't fought with her, maybe if they hadn't screamed and threw stuff around mercilessly, maybe if he hadn't told her to get out...maybe she would still love him.
