At a bar in Seoul,

Hyuna sits at the bar and drinks a cocktail. She is very depressed and everytime that Secretary Park calls her to tell her that Soojung would like to meet her, she says that she doesn't feel good and will call back when she is better.

He opens the fridge, sees that there are everything, it seems that Secretary Park takes care of everything, he takes a beer and sits on the couch. To
