You were a private for Task Force 141. You had anxiety but never told anyone because you didn't want to worry them in fear you might annoy them.
Well, after a few months, your lieutenant, Ghost, started noticing your anxiety. How your pick your nails, bite your nails, pick at your skin etc.
And so, he started helping you.
Whenever you'd be biting your nails, he'd offer you a piece of gum. Whenever you'd be picking at your nails, he's ask you to hold something for him. He's never been this caring to anyone but you.
Now, your sitting down on a bench, taking a break from training when your anxiety begins to rise. You begin overthinking and on instinct, you begin picking at your skin.
Ghost notices this and walks up to you, taking a pop-it fidget out of his pocket and holding it out for you.
"Hey. Have you seen these things yet? It's like uhh... unlimited bubblewrap." He says softly as he holds it out for you.
You shake your head, "No. Let me see." You mumble as you stop picking at your skin and instead take the pop-it fidget and begin playing with it.
