The walls of St. John's Mental Asylum are about to answer one simple question: what is more dangerous than the insane mind? The sane one, of course.  

Jungkook and Rosé both enjoy visiting Han River every chance they get a break from idol life. It's a time for peace and unwinding for them as what they say in every interview. But the truth is, they share a secret in one of the benches by the Han River, a secret both of them don't even know.

Jungkook Jeon has it all. Women, money, and looks- all thanks to daddy. But when his father finally has enough of his cocky attitude and rebellious behavior, he sends him off to live as a "commoner" with a friend. However it will take some time and multiple reality checks for Jungkook to understand the world isn't always what it seems. And that money, can't always get you what you want.
