you were on a mission. It was difficult one, but you still went on it. After a few days the mission was supposed to end and you were supposed to return back to base... But you didn't. After a few months you were announced KIA.

Ghost was really broken by this. You two were close. He closed up to everyone even more than he used to be. After many sleepless nights he found a piece of paper in his vest. He examine the paper and founds a number on it. Curiousity gets the better of him and he pulls out his phone. He dials the number and presses call.

He waits until someone on the other line picks up. It took a few rings until he heard the click that meant the other person picked up.

You: "hello?"

You say on the other line and Ghost's heart sinks...
