Ghost x Reader/Mackenzie Graves

You're Philip Graves' little sister. He got you into the army after some family problems, and you're both skilled soldiers. One day, General Shepherd wants you to join Task force 141 to capture some terrorists with some of the best soldiers while Graves stays with him to help with top secret missions. You agree and join 141, not realising what you've gotten yourself into. Humiliation and pettiness from a masked man..? And upcoming betrayals? This was gonna be tough.
