i think the fluffiest we've got is louis and amelia (@malumxsubest) just because he's insanely soft for her and that's his wife. his most beloved. she can do anything and he's instant heart-eyes. they're equally powerful enough that even if they wanted to fuck with each other in some antagonistic way, it'd just be for funsies unless... she actually wanted to kill him. she's got the power for it, but he'd just come back later and probably adore her for that, too. talk about how sweet it is that he means enough to her (or pisses her off enough) to kill him with her own two hands. he remembers the time she put him on his ass during their first meeting very fondly now. he didn't in the moment, but now it just makes him love her even more. he is completely and utterly devoted to his feisty deity wife!! she is god to him in every way.
otherwise... micah and annie!! hands down. he's been insanely heart-eyes for her since the day they met, and he just adores her so much. it started as just that "oooh vampire curiosity" and then it grew from there and he got attached really quick. i don't think i've ever written anything more fluffy-feeling than micah/annie, and that's wild to me because micah is not a fluffy person. she said once that she doesn't want to change him and that hit hard because there's always something people want to change, but she accepts him exactly the way he is and it gets him every time he thinks about it. as a human, annie gives him that sense of danger he's always chasing and makes him feel safe with it, safe enough to feel it and talk about it openly in ways that he usually couldn'tāor wouldn't. they're just so sweet on each other honestly, and with annie, he's actively putting real thought behind his actions with her and the things he says in a way he would never offer anyone else. he's not very good at words, especially in a romantic context, but he tries so hard for her. on any normal day with any normal person, he doesn't respect boundaries, he doesn't give a fuck about how they feel, doesn't care how his words might effect them, but with annie he really does. or at least he tries toāand that means everything for micah. he's never said it before because he's a scared little fuck and doesn't know how quite yet, but he loves her so much. so much that he'd actively try to change for her if that's what she wanted and that's never happened for him before!!
