Fushiguro and Itadori were just messing around, talking laughing and playing in their dorm. and the conversation of pointing things out about each other came up at some point

itadori, stood in front of megumj, gently reached forward and touch at megumi's waist and hips "...your hips are really small" he pointed out, which made megumi tense and blushed slightly

"...you really dont know what personal space is, do you...?" megumi pointed out, leaning in

"people tell me about that alot haha"yuji admitted

"...hmm... well you do have a nicer body than me even though i'm taller than you..." megumi pointed out, his hands sliding from their resting place on yujis shoulder to his chest, squeezing softly "...im kinda jealous"

of course, this flustered itadori, his head slumped into megumis chest as he went red, gripping his uniform

"maybe i should work out more..." megumi began, before noticing "...itadori? you okay?"
