Chuuya always had a slightly more.. feminine body to put it lightly, he's short, way too short for a guy his age, tiny waist, and a feminine face, he was always angrier for a few days once a month, one could mistake him for a girl. Sure, he's a great fighter, he could wipe the floor with you and he isn't afraid of doing so. And you, as his best friend, were always a victim of chuuya's outbursts, punching, kicking and hitting you was his way of showing his love.
Yet, you've never expected chuuya to be...well not biologically a man, but he's a man, more man than you would ever be. You walked on chuuya changing, because you never knock and he knows that, you walked on him changing of his shirt, leaving him in only his binder. You both just stared at each other for a couple of seconds, not daring to break the silence, chuuya himself was the first to speak.
"You act like you've never seen a trans guy before." Chuuya said in annoyance.
