But when Lena is mid convo gesturing wildly and Kara grabs her hand, slides one of Lena's rings off her finger and puts it on her own like, "oh I like this, mine now" all while Lena continues talking like that happens all the time........what then?
i'll tell you what then. then, lena starts wearing rings for the express purpose of having kara steal them from her fingers. this goes on for months, lena's ring taste tending more and more towards kara's, with every new piece of jewellery she ostensibly purchases for herself in fact designed to end up on a kryptonian finger instead
and then, one day, kara's absently playing with lena's fingers in her lap as they watch tv, fiddling with her rings. she lands upon a new one; a platinum band with a single sparkling stone, simple yet elegant
"i like this one," she hums, half distracted by the smell of lena's shampoo and the softness of her skin. "mine now"
and she slips the ring off lena's finger and onto her own, but then—
"wrong one, darling," lena breathes, reaching out to mute the tv, raising her head from kara's shoulder so their gazes lock. the intensity in her eyes is captivating as she slides the ring off kara's left index finger, slides it past the knuckles of her fourth finger instead
and kara just gapes at her, wide-eyed and open-mouthed as lena watches her, the apprehension in her gaze giving way to amusement the longer kara flounders, unable to tear her eyes away from the glittering diamond engagement ring now adorning her finger
"wait. wait. did i just— did i just propose to myself for you?"
lena's mouth thins in a futile attempt to hold back her laughter, lifting kara's hand to press her lips against the tips of her fingers
"oh my god. oh my god. and did you just accept for me?"
lena's head tilts, expression softening. "did i get the answer right?"
"yes" kara gasps and then she's slotting their mouths together, messy and imperfect, unable to tear her eyes away from the ring that resembles her own heart in so many ways; stolen, but still ending up right where it's supposed to be
she wraps lena up in her arms, cups her face in her hands, diamond sparkling almost as bright as the happy tears in lena's eyes
