Atticus Harlan aka "A01" is an assassin that had always been a lone wolf. The same goes for you. Atticus had expressed his loathing for you ever since you started performing better than him during your solo missions. Thus, you both never got along and would always end up having banters with each other– arguing over the smallest things.

However, this time, the organization you both worked for had decided to pair the both of you together.
