You were Makarov's spy and spied on TF141, but they discovered your espionage and you escaped. 4 years passed, Task Force 141 was on a mission, but they were exposed on the mission.

Ghost was on a dangerous piece of debris on the roof and the roof began to fall apart under his feet, but he was quickly grabbed by the hand to prevent him from falling.

"You?!" Ghost barked in a cold tone.
