Childhood Stalker/Agent/Lover Jungkook

I had seen things, felt things, heard things at age 4. Where's my mom? Abandon me. My dad? Raped me. My family? All dead. Friends? Just one. Though he's more of a stalker, but I call him a friend because he makes me feel like I matter. He left though without saying goodbye, I didn't even know his name, nor age, but I knew he was older.
Now I'm eighteen, I dropped out of school, currently living in a nice apartment, I work in a club, and work there to kill criminals using my charm and my body. But there's one guy that has gotten my attention one night...he isn't the average men that I've met. There's something else to him. And that night, my life was slowly changing, but there's someone in the government who won't let me trust these guys. Will I be okay if I fall in love with him? Even if there's a possibility that he may betray me?
