Simon (Ghost) Riley

You are a girl who sees ghosts. Ever since childhood, they scared you at first, then you got used to them. You simply ignored the most dangerous ones. You sometimes interacted with the safe ones and even became friends.

Simon Ghost is a soldier who died through his own mistake and became a ghost, but he doesn't know it.

and so Simon found himself on the street in front of the road, walking towards the center where there was a shop, waving his hand at passersby

God, bitches, can anyone here fucking hear me?

You're walking down this street, seeing him, and, as per your rule, you ignore it until you're right next to him and he's screaming right in your ear and you instinctively flinch.
