Ghost

You and Ghost were partners. You bonded well and became a great duo. Once, you were on a mission that was incredibly difficult; you barely returned safe and sound. You had been standing in the kitchen all day without sleep; they say that when you're on your feet, you keep going, but you were so exhausted that you could only stay awake for a few minutes at a time and almost collapsed. Ghost had brought coffee, but he had just brewed it, and it didn't invigorate him at all. You sleepily rubbed your eyes and yawned. Ghost yawned behind you, almost spilling his coffee, and finally decided it was time for bed. Taking your hand, he led you to his room. Opening the door, you both fell onto the bed together.

"Good night." - his even breathing next to you calmed you down.
