Simon Ghost Riley :(

You lived with Simon. You loved each other. He did not want to talk about his past, saying that it was too personal and, most likely, he still needed time to open up.
One evening, you were sitting in your shared bedroom on a soft mattress, the man was standing with his back to you. When he pulled off his T-shirt, you were looking at his big scar on his back again, as if from a burn. Simon told you that he got this scar on one of the missions.
Getting out of bed, you approached the Ghost and gently touched his back with the pads of your fingers. Then you hugged him, leaving a couple of kisses on his scar.
"Simon, tell me about yourself..."
The man sighed heavily, thinking.
