boyfriend!aki, who slips into domesticity so naturally it almost tricks you into forgetting the danger he wades through daily. the muted clatter of knives against the cutting board is its own kind of reassurance that he’s here, with you.
boyfriend!aki who kicks denji and power out of the apartment under the guise of “cleaning,” which they definitely don’t want to help with. but really, it’s just so the two of you can finally have the privacy to fuck nasty.
boyfriend!aki, who is in an oddly good mood after you’ve slept together. power will wrinkle her nose and tell you she can smell the “mating smell” on him. aki ignores her, but the tips of his ears go red every single time.
boyfriend!aki, who humours you by letting you tie his hair, and even when it comes out crooked or uneven, he leaves it be, letting gravity decide when it will falls loose on its own.
boyfriend!aki, who flicks his cigarette into the ashtray mid-drag the second you call him inside. because lets be real, between nicotine and you, it’s never a contest.
boyfriend!aki, who hangs onto the smallest mementos of you—movie stubs from the nights you went together, the receipt from your first official dinner date, even the wildflower you once playfully tucked behind his ear, now dried & pressed in a book.
boyfriend!aki, who is deceptively gentle in the small intimacies such as undoing tangles in your hair with careful fingers.
boyfriend!aki, who sometimes calls you late at night when you’re apart on missions, asking about your day while his free hand works under the waistband of his sweats.
boyfriend!aki, who will most definitely beat up denji if he says something inappropriate (albeit on accident), because boundaries exist and he doesn’t negotiate when it comes to you.
boyfriend!aki, who texts concise and to the point: “what do you want for dinner” or “don’t stay up too late” and checks his phone almost obsessively whenever it pings, just in case it’s you. and if you text “i miss you,” he replies simply, “i’ll be home soon,” and then, placed strategically almost as an afterthought, “miss you too.”
boyfriend!aki, consent king, who always waits for a clear yes before pushing a boundary—because he wants you to feel comfortable and wanting it as much as he does.
boyfriend!aki, who sometimes cries after sex.
boyfriend!aki, who is nearly impossible to coax into a heartfelt smile, and yet you’re the only one alive who’s seen it.
boyfriend!aki, who is the big spoon on default but doesn’t mind (and secretly enjoys) being the little spoon.
boyfriend!aki, who likes seeing you in his clothes.
boyfriend!aki, who sighs in exasperation when he sees you asleep on the couch again. but the annoyance never lasts. he kneels beside you, lips lingering against your temple as if to say thank you for waiting, even when he told you not to.
boyfriend!aki, who carries the knowledge of impermanence everywhere he goes, and so he loves you without holding back.
