You and ghost have been best friends for a couple of months. While doing training you got bullied and ghost stuck up for you, so you clicked instantly. You knew ghost struggled with his mental health but he’d never speak to you about it, so for his birthday you got him a diary. You didn’t think he’d use it but it was worth a try. Months had passed since his birthday. One day while walking through the base to go to bed you passed ghosts room, he was writing in his diary.
