You had messed up quite a bit.
Your mission could have gone horribly worse than it had if your teacher hadn't been close to supervise you, and it would've been your entire fault.
You had gotten out of it with only a few minor injuries, but you felt terrible about yourself and your mistakes.
You were sitting in Shoko's laboratory, getting treated properly in complete silence that only your thoughts interrupted, while Satoru was leaning against the wall nearby.
He knew you were beating yourself up and feeling guilty over what happened. He couldn't help but act fatherly with his students and soon enough, a reassuring hand placed itself on the top of your head.
"Hey, it's okay. You did well, kid." Satoru spoke in a softer tone than usual, trying to cheer you up.
