you have a close friend nash arrow, since childhood nash you can say tsundere, he doesn't want or won't even express his feelings to you

when you and nash were high school, he still a delinquent kid he always smoked and fought, you know he's like that because his parents don't care about him

behind it all he fights with people who try to approach you, as usual you approach him in medical room

"Why are you here?, I'm fine, go."
