dabi is the most sentimental in the dark.
it's during those quiet, rainy nights where you learn how soothing his voice can be. after the first few months of knowing him, you had learned that he doesn't usually talk much, and when he does, it's usually snappy quips or dry remarks that don't come from the heart, and the gravelly sound of his voice that carries throughout the room isn't usually described as... comforting by others.
but to you? his voice is the fire in the most frigid cold, reassuring and familiar in all the ways that feel like home. you could listen to him talk for hours.
"—and there's all sorts of superficial convictions heroes have, and i'm not sure what pisses me off more, their stupid costumes or their empty promises. that kinda stuff isn't worth being put on a pedestal, you know?" he murmurs, palm traveling up and down the length of your spine idly as you let out a sleepy hum
"you better not be ignoring me by falling asleep." he snaps suddenly, and your lashes flutter open with a breathy giggle as you quickly move your head in a lethargic nod to acknowledge his prior words
"no, no—i'm listening. and i get what you mean, i like how you search for the realest parts of everyone. and the people that are full of the strongest of convictions. just like yourself." you coo, and dabi lets out a huff before drumming his fingers against your waist in silent thought
"you're right. and you should always chose the people you trust carefully." he replies monotonously, staring up at the ceiling with unblinking eyes. you sneak a peek at his side profile, lips twitching as you observe the serious look that's overcome his face. you like when dabi gets like this—comfortable enough to share his thoughts, his opinions—comfortable enough to let you peer inside all the chaos that is his mind.
"is that how you and i are together? did you see how real i was, how true i was to myself and most definitely to you?" you grin, poking his cheek playfully, and dabi's head tilts down to meet your gaze before a slanted smirk tugs the corner of his scarred lips upward
"nah, you just wiggled your way through the cracks. like a cute lil' sewer rat."
he barks out a laugh when you smack his chest before shaking his head — "no, no. 'course i chose you myself. i wouldn't let just anyone sleep in my pathetic excuse of a bed like this." he comments dryly, waving a hand around and gesturing to the darkened room you two occupied. you laugh brightly as you pull the thin blanket around the two of you tighter, hair spilling over your shoulders as you hover over his form
"it may be a twin mattress too small for even just one person, but that just means i get to be all the more closer to you, right?" you beam, and he rolls his eyes so far back and dramatically that you can't help but giggle at the sight
"don't get cheeky." he mumbles, pulling you back into his arms as you fall against his chest with a muffled oof! — then, dabi presses a hand to the back of your head and stuffs your face into his chest a moment later
"now shut up and go to sleep. any more giggles out of your mouth and we'll be up all night."
dabi flushes immediately at the nickname, blue eyes widening a fraction before he scowls down at you and pinches your waist. you yelp, and he huffs before reaching forward and placing his mouth on your own, offering you enough gentle pecks to melt away your little frown
"goodnight." you murmur once satisfied, and the arms wound tight around your waist loosen with time as dabi fell into a deep slumber, body gone slack beneath your own, and the only sound you can hear is the gentle thump of his heartbeat against your ear and the distant ambiance of the rainstorm outside
