he feels a little silly sometimes, always staying at your place instead of having you over at his.

atsumu can't remember exactly when yours started feeling more like home, and his more like somewhere he needs to stay sometimes when you're busy and he needs to work, too. he makes the excuse that your bed is bigger and more comfortable, with your "hundreds" of pillows and soft, soft blankets (he wonders how he'd ever fit comfortably in his own bed alone all this time, much less entertained others, not that anyone before you could be compared - it feels too lonely now, anyway, on the nights he's relegated to needing to sleep alone in it) but he doesn't think it matters in the end, because any free time he has, he's at your doorstep, usually with a snack, treats from his brother, or your favorite drink.

he thinks he falls in love with you all over again when you decide to give him his own key.

atsumu crushes you in his embrace, needs you to breathlessly shriek at him that you can hardly breathe to remind him of his strength. he settles for peppering kisses all across your face and jaw and neck until you're pushing him away playfully, laughing, an irresistible tinge to your skin, glowing with love. he assumes he looks the same, he feels it blooming deep in his chest and hopes you can see it just as plainly on his face, every facet of his being.

"you in love with me or something?" you can't help but tease, though the answer is plain as day, carved into his handsome features and sparkling in his eyes.

"very much so," he replies anyway, beaming at you, then the tiny cut of metal in the palm of his hand that he thinks he'll cherish forever, long after you've moved out and he's put you both in an even bigger space - a shared one, officially. the thought makes his chest warm.

atsumu all but sprints to latch it onto his keyring, then grabs your hand excitedly and leads you to the door. "c'mon, baby, i gotta make ya one for mine, too."

one day, you'll both only need one set.

he pauses at your doorway, turning back to you and kissing your wrist, a gesture that never fails to make you smile. "this really means a lot to me. and, you're never getting rid of me now." he winks, and you giggle.

"i wouldn't dream of it, 'tsumu."
