Okay so you know how Killua is like a fashionista? Where his clothes are always so cool (and at times questionable)? So like imagine that Gon compliments Killua on his sense of fashion ALL THE TIME. Like “Wow Killua you look so cool!” “I wish my clothes looked that cool!” “When we get more money we should go shopping together!”
Then they spend a night together when it’s super cold. And Killua whips out these FREAKING FOOTIE PAJAMAS. And he’s so proud of them. And Gon is just so confused??? Like when did his fashionable best friend become a dork??? And Killua is SO OFFENDED when Gon doesn’t compliment them.
