Looks Like Bro Code Does Not Apply Here

Luna Black the world's top femme fatale has found herself in deep shit, by literally attracting 4 mafia brothers romantically, and she does not know what to do. Now she has to decide if she keeps all of them or chooses one without getting herself killed in the process. You might be wondering how she ended up here, well let's just say she is one of the many people whose lives were in the hand of the Achilleas Twins like seriously there is a bomb in her brain that will go off if she betrays them or breaks her pledge. What happens when Nyx Achilleas sends her to a Russian mafia ball to spy on the Kuznetsov family and she ends up with four huge barbarians trying to get a piece of you. Well, she can do the only thing she can do which is disappear, unfortunately for her they love the chase and she loves them chasing them.

Snippet:
Oh my God, I just saw one of the brothers at the mall, they found me sooner than I expected looks like it's time to hide again because if one of them was here the rest were around. I ran into my room and taking my pre-packed for instances like this, where do I go next? Will I have time to get a flight? Who am I kidding, I own my own fucking jet, perks of the job.
BAAM!!!
"What do we have here, brat'ya (brothers). Looks like she has no way to go" Ilari smirked at me, look at how sure he is after knowing me for 5 years he still thinks I won't find a way to escape. I looked at the window behind me that was already open I smirked and looked at him, his face quickly lost its smirk but before he could reach I was already out.
