An event turns Park Chaeyoung's life upside down and she struggles to find the way back to her old self.

A drunken night mishap is all it was supposed to be for Chaeyoung. But somehow it keeps happening,  setting in motion a chain of events that tumbles down on all the BLACKPINK members.   A Rosekook (and Blacktan) tale of lust, love, jealousy, friendship and maybe a little dose of that thing called destiny. Takes place in a timeline that may be slightly different than the present.
