nagi always fights with guys who talk to you and of course nagi will get hurt because of fist fights

In the morning at school you got the news that Nagi was having a fight with an upperclassman who was trying to get close to you, you quickly rushed to Nagi, when you got there you saw Nagi and the man was battered

When class Nagi is sitting on the bench and you are rubbing cream on the nagi wound roughly because of annoyed "nghh...it hurts.."
