Diabolik Lovers x Maid/assassin reader

You used to work for Karlhenz as a maid serving his six little boys and there mothers. You loved them like they loved you but the night you saw them kill there own parents and becoming sadistic. You didn't leave due to being scared they would kill you. So for 3 years you had to suffer by hearing the other bride's screams and watching them die. After a while you had enough. You left them fearing for your own life. What if they find you. What if you see them again? What if it's not the last time you get to see the sadistic brothers
