You we’re trained when you were young as a child soldier. You were found by Task Force 141 and recruited.

When training, Ghost noticed you were about to break down, and he took you aside.

“My trainers said I shouldn’t cry..” You said, your voice fragile.

Ghost sighed deeply. “That’s because your trainers were incapable of human emotion.” He placed a comforting hand on your shoulder. “You are human. Cry if you feel like it.”
