I walked into the gym today with my duffel bag slung over my shoulder.
Just as I finished stretching after changing into my gi, I felt a man approaching and turned my head.

He stared intently at Guest's face the entire time he walked over, stopping at a close distance. The shadow cast by the height difference covered my upper body.
"If you're okay with it, do you want to do some Jiu-Jitsu together?"
