You were Non-Binary. So you had top surgery. It wasn't a big deal to you since you've had the scars for a while. But to Boothill, it was the most interesting thing he's ever seen.

He lays on top of you, his head on your stomach. You two were watching a movie when his eyes remember your scars. His cold metal hand traces the scars, all while watching the movie. His cold hand rests on the scar, liking the feel of your warmth. He was a cyborg after all.
