50) who's more likely to do something out of spite?
Both of them lol
51) What’s a non verbal way they say I love you?
Graphite bites Kiriya or gives little headbutts. Sometimes just stands behind him and holds him while Kiriya cooks.
For Kiriya it's cooking or baking stuff Graphite will like, but also introducing him to foods he grew up on that might not be as conventional.
Also kissing of course for both of them, and Graphite attempting to cook Kiriya's favorite foods, or Kiriya adopting some dragon affection signs from studying Drago Knight secretly on his own to surprise Graph.
52) Describe their weekend getaway?
I think either going to the beach or to the mountains. Somewhere to be away from the city and just be together in nature.
53) Would they ever go skinny dipping?
Graphite definitely. In Drago Knight his default state was naked because he was born and spent most of his life a dragon (at least in most of my headcanons) Graphite and Kujo "will try anything at least once" Kiriya? Absolutely.
54) Who’s more likely to carry the other to bed?
Graphite carrying Kiriya. I love headcanoning Kiriya as someone who loves to be carried and will just frivolously request it a lot. Graphite sees it as absolutely frivolous but kind of likes showing off his strength, even though carrying Kiriya isn't hard at all.
55) Do they like watching clouds or star gazing?
I think both. Graphite's more of a star gazer, and Kiriya's a cloud watcher, but they'll indulge each other in each other's interest and just like lying down and chiling together.
56) What do they do turn the other on/put them in the mood?
I think Graphite's very tactile and visual. Like, I think Graphite has very specific aesthetics he enjoys so Kiriya will wear certain things or touch him in certain places and ways to try and tease Graphite. Also depending on the version of Graphite I'm writing, he might be very scent oriented as well and just like burying his face in Kiriya's neck or shoulder to smell him. For Graphite to Kiriya, I generally think it's like, biting and light scratching. Graphite bites Kiriya to silently tell him "horny" and Kiriya's really into it, especially on his neck and ears. Also dragging his claws along Kiriya's outer thighs and the sides of his waist. Graphite's not super into music during, but he knows Kiriya has a few playlists so he might put those on as well.
57) Whose the serious one when grocery shopping and who likes to toss random things in the cart?
Since I often headcanon Kiriya as the son of restaurant owners and being very proud of his cooking abilities, I think he's "serious" about it. Like his shopping style is very casual and he's open to getting ingredients to experiment with. But if there's a sale on green onions, he's getting those fucking green onions and everything else on the list he came for. Also I see Graphite seeing packaging that catches his eye and just tossing it in not really knowing what things are, or wanting to try all kinds of new desserts and snacks that he eventually gets really picky over the quality and taste.
58) Who’s more likely to hold a grudge after an argument?
I think they do it in different ways, especially depending on what the argument was about. I think Graphite shows it more outwardly, cold shoulder, or pointing things out related to the argument in other random things, trying to circle back to it and win, or just trying to make it into a physical fight to better express himself. Meanwhile, I see Kiriya playing things out more passive aggressively, just being overly nice and smiling, but getting in little jabs here and there that take Graphite a second or two to figure out the actual meaning of.
I don't see them holding post-argument grudges often since Kiriya's generally a chill guy and Graphite sees more merit in honorable fights, but sometimes they just find that weird little hill they're willing to fight and die on together.
59) Who tops? Who bottoms?
They're both switches in my mind, but I do write Kiriya bottoming a lot more. I'm hoping to even it out in the future because I did think about Graph bottoming a lot at one point.
60) Who pulls the other closer when they’re sleeping?
I generally headcanon Graphite doing it more. Depending on what version of Graph I'm writing, he does it partially out of 'protecting his precious hoard' instinct. Otherwise, he's doing it because he's usually the big spoon, or doesn't sleep and instinctively wants to keep Kiriya closer for easier protecting in a more guardian/bodyguard kind of way. But I think in some versions of their relationship Kiriya's the one to do it because he's often the one initiating when I write a bit of a "shyer" Graphite. Basically, a Graph that isn't super familiar with intimacy yet and is okay with letting Kiriya take the reins while trying to maintain his intimidating and cool image.
