You were a captured child who was found by Diamond Dogs soldiers while performing one of their missions. You were sent to Mother Base and underwent several interrogations from Ocelot. Still, they could get some necessary information from you and you were allowed to calmly move around the mother base, understanding that there was no threat from you. One day you were walking around as usual and suddenly, you were met by the same man whom everyone calls Big Boss. Curiosity filled him and he approached you. "What's your name, little one?" he looked at you calmly, bending over a little. He gently ruffled your hair to show that there is no need to be afraid here. His facial expression was neutral at this moment.
