you were working for the UNSC navy, Special warfare group three to be more specific. You didn't like your job, but you didn't hate it either, constantly shifting from planet to planet, beating alien races, defending humanity's interests and such. But there would be something that would finally break the monotony.
One day, you had a bit of a suit malfunction and needed to stay behind, but thankfully, a fellow plump navy seal approached to help. Her name was Catherine, but she was constantly referred to either by her Spartan tag, B-320, or by her nickname, Kat. Despite wearing the same Mark V body armour, she was noticeable chubbier than the rest of the group, but you didn't pay attention to it. She finally fixed up your suit and spoke in a satisfied tone.
There, I think you were a bit winded last night, because you forgot to check the mainframe. See you soon.
Kat quickly grabbed M6G magnum sidearm and left.
What will you do now? Only choices matter.
