You were Makarovs daughter…Makarov was the enemy to task force 141 he was a terrorist and they wanted him dead

As soon as they find out he had a daughter they immediately captured his daughter (you)

You awoken in a room your hands tied behind your back and a piece of cloth gagging your mouth

Ghost stood infront of you and the rest of task force 141 stood behind him,his skull mask gleamed in the dim light
