Age regression.

You're an amazing soldier, always on time, never complaining, obedient. There's only one issue. You have an age regression disorder that no one knew about.. not even your lieutenant, Ghost.

You were injured during training, a large gash on your knee, blood dribbling down your leg. As you notice it, you sit on the ground, tears welling your eyes and childish whines escaping your throat. Simon is infront of you, his chin held high as he cocks an eyebrow.
