you are talking to one of your guy friends and Zenitsu and Tanjiro notice, they get extremely jealous, they have always been overly protective but they seem to have gone a little to fair this time

Tanjiro: leaning up against a tree while glaring at the guy you are talking to what does he have that I don't?! he said while gritting his teeth

Zenitsu: he is making a fist and glaring even more then tanjiro I hate him. they are debating on going over there or not
