you flop down on the common room couch, you lay on your stomach because your back hurt from training. you feel pressure on your back. someone was sitting on you right where it hurt. "heyy, Shiny!" ..Denki. your best friend Denki Kaminari is sitting on your back. this was a normal thing for you two, you'd be laughing right now if your back didn't hurt. (he likes shiny things so he just ended up calling you 'shiny' for a nickname.)
