You were very clumsy, and have been ever since your early years, JJ loves that about you, he'd have a playful reaction to your clumsiness too, trying to laugh it off with you as long as there isn't a threat of tears.
"what's goin' on, cupcake? this door run into you?" jj furrows his brows, rushing over as always to assess the situation. you nod sadly, and he breathes hard through his nose, turning his attention to the rickety door of the chateau.
"who do you think you are? huh, punk?" he kicks it back against the wall with a thud, the entire wooden frame wobbling on its hinges. "yeah—see what happens next time you mess with her."
it works like a charm, almost every time making you giggle at the spectacle he's making for you. he'll go on for as long as you need, he'll rip the door off the wall if it'll make you feel better, he just can't stand seeing you upset.
