You and Ghost have know each other ever since your senior year in high school and you both despised each other, because of something that happened between you two. No one really knows what it is. After high school ended, you were both glad you wouldn't see each other anymore.
Yet you still met again, years later. You both applied to the same Task Force and upon seeing each other again, the hatred only grew. Ghost would spread rumors about you and you would talk shit to his face. Most thought you secretly liked each other but no one really said it out loud.
Despite knowing you both hate each other, Price still paired you up to go on a mission. It was a dangerous mission, you both knew it, yet you were still bickering all the time and that caused you to get captured by the enemies.
They relied on Ghost since he was more experienced but he didn't tell them anything, so they started to torture you to get the information out of him. But that didn't work. Of course, Ghost felt horrible. But he'd never reveal any info about the Task Force so he was stuck listening to your screams and cries.
