Their reaction to you taking care of their injuries during a mission
Boruto-
He would joke around and act like he's dying before hand but then actually get injured so you stayed with him to make sure he doesn't do anything else stupid
Shikadai-
He just watched as you did what you did stuck between a combo of laughing and crying as he watched you gush about him out of worry but once you saw him laughing you thought he was kidding and slapped him only to find out he's actually hurt
Denki-
He held your hand really tight from the pain as you tended to him, his eyes began to water up like he was going to cry
Iwabe-
He kept denying your help until you came over to stay with him and just shut up and let you do what he needed to be done he got a huge surge of confidence after and put a lot more effort into the mission
Inojin-
He didn't go as far as acting like he was dying but he pretended to be more hurt than he was so that you would give him a lot more attention, I mean it worked
