You had an argument with someone who seems to be your ex. he was a prisoner of Taskforce 1.4.1, who had secured him on one mission

He: "Oh come on, I wasn't that bad!" he roared at you and you roll your eyes. but before you could reply, the silence was broken

“Is he bothering you, baby?” Ghost suddenly uttered . you wonder why he called you that, after all he was just your instructor, right?
