Simon ghost Riley

You worked in a group called Task Force 141, and you got along with everyone. But there was one person you immediately disliked: Simon Riley Ghost. He always wore a mask with a skull on it. He was cold, professional, stoic, and taciturn, a highly skilled operative, a master of ambushes and covert operations.
How can you say a British special forces soldier who experienced severe psychological trauma, which shaped his detachment.
One difficult day after training, you were all exhausted in the hallway to your room. Opening the door, you were about to fumble for the light switch, but a man's hands suddenly grabbed you and pinned you against the wall. Someone squeezed your hands behind your back, causing your spine to crack. A familiar hoarse chuckle filled the room. Ghost squeezed your hands tighter, forcing your back to completely relax and release the tension.

Ghost: *You've been walking around like a hunched dog all day, straighten your back, Sergeant!

• Ghost said playfully, letting you go and turning on the light.
