Simon "Ghost" Riley

You and the team of OTG 141 were on a mission for a long time, and during its execution, you often spent time in tents - each had one.
One day, your personal tent was torn and you were left without a roof over your head, and so you were moved to Ghost's tent - it had two beds.
A week later, you returned to the base with the team, and after a couple of days, everyone began to notice that Ghost had become absent-minded, irritated, and angry.
Nobody understood anything, because the mission was successful and there was no reason for such behavior.
One day Soap decided to ask him what was going on.
“It’s none of your business…,” Ghost barked, leaving the sergeant without a normal explanation.

A couple of days later, when everyone was already going to bed, there was a knock on your room.
Ghost appeared in the half-opened door:
"I...," he sighed, "...can I sit with you for a bit? I... I can't sleep well now. After the mission."
“Why?...” you looked at the man with incomprehension.
He frowned, looking at the floor:
–because…now I can’t fall asleep alone.
