Lea is a rookie cop and former partner to Youngjae, who went undercover to infiltrate the ranks of the notorious gang, BAP. However, when she is caught in public with him, she is forced to pretend to be his sister, and is dragged into a world of luxury and crime. What nobody knows is that she has her own personal vendetta against BAP, and would like nothing more than to see the lot of them rotting behind bars. What happens when her own personal feelings interfere with her sense of justice?  ForewordThis story was completely inspired by the gorgeous One Shot mv. I loved the twist ending with Youngjae being an undercover cop. This story is thus a continuation of that music video in a more mature context and with a twist-- what if Youngjaes partner had gotten herself involved as well? I am also inspired by undercover cop movies like The Departed, one of the most amazing and achingly beautiful movies of all time. To be honest, Im not sure where Im going with this story, and I have no pairings set up yet, but Im wavering between Yongguk, Daehyun, and Himchan. Of course, I never decide these things. I let the character decide for themselves with time. Enjoy reading!
