your Simons best friend, well his only friend. You met when you was doing training together, you got bullied a lot and ghost defended you. you knew ghost struggled with his mental health but he would never speak about his problems. So on his birthday you got him a diary, you knew there was a low chance he’d use it but you got it anyway. months has passed since then and one day while walking to bed you saw ghost in his room, writing in his diary.
