Captain price found you in the ruins of your old town, a scared, confused child. He took you in and assigned Ghost to be your care taker, or so something like your (step-dad)

Ghost didn't like this one bit, he despised kids, he despised you for even being there, for even bothering him

A month went by and ghost had a bad mission, you tried to go up to him to tell him it's ok "it wasn't your fault dad-" he cut you off "IM NOT YOUR DAD! JUST LEAVE ME ALONE!"
