I've always been really intrigued by the contrast between his social mask and the obvious signs of... what should I call it, dishevelment? The more you find out of his character or take a close look. One thing being that his haircut is a bit uneven and seems roughly pushed away from his face in his sprite, both in flashbacks and in the main game. I find the same contrast interesting in Mishima too, especially since in-universe he seems to have a harder time being perceived as put-together or reliable until one gets to know him despite, in my perception, trying very hard to keep up a "responsible" image to people in the same way. <- rambling because it remembered that it likes YTTD

yes!!! it's so interesting to me - you see them both try very hard to keep up an (effortless) act that would poise them as, well, reliable people! as you said. despite them both still being very supportive and compassionate people beneath the appearances they put on, neither of them really seem to recognize that as worthwhile (or at least, not as typically palatable, which especially applies in kazumi's case despite his best efforts :[ poor fellow...)
i actually spoke the other day on how these two's speech patterns in particular were almost... the inverse? of one another as well, which plays into what you mentioned here too. all sorts of things help them form their social masks...
kai does seem to speak very straightforwardly in his mind - with some silly similes to spice it up ("kai, your mood is as unusual as the autumn sky"). but aloud, even though he's concise, he will usually softens his words with phrases like 'may, might, perhaps' or preface with questions to reaffirm what he's been told before he actually approaches an answer/response. he's rarely brazen unless he believes there's danger (the only times you'd even see him raise his voice in-game is when he's trying to get sara's attention, at the threat of death) - he tries to keep himself composed for the most part!
but like you said, as you learn about kai or get closer to him (ytts is really good for this), you do start to see the cracks begin to show. he's still very much learning how to... be a person, not just an extension of asunaro. it's what contributes to that subtle disarray, because you see the him wear his asunaro uniform (which he couldn't discard, because it still feels to be an intrinsic part of him despite years spent with the chidouins), contrasted with the apron (which he wouldn't discard, for it is cherished). and while he's clearly grown to accept and even enjoy having long hair now, he hasn't yet learned how to take care of it.
it really is interesting seeing these small signs of him still piecing together what his life, who 'kai', could be! and when people like kazumi, reko, nao dig a bit deeper because they want to know kai, they see more of those uncertainties that he learned to mask. it's really touching seeing the moment where kazumi begins to unveil him in a very kind way and kai ends up asking him to stop, because it's such a large step in trust that kai wasn't prepared for...
that scene always hits me :'] yours are hands filled with affection toward another... ahhh.
& then you see what kai does for kazumi in return too... because, despite the occasional 'you really are a bit [intense] aren't you' -- it isn't necessarily a bad thing! just an energy that kai wouldn't usually match, but is nonetheless unique to kazumi himself. and for that, kai insists to him that perfection isn't what he should be seeking out, but rather he should concentrate his efforts foremost on his skills and passions; hone in on what only he can and present that to the world irregardless of people's more superficial reactions toward his appearance or how he presents it. which is really what kazumi needed to hear, considering he started out the event with:
I wish I were a truly fine teacher, the kind who could answer any question I'm asked… Right now… it feels like I'm just barely managing to teach art and how to study…
which, getting back to how they phrase things... for kazumi, you can see the shift of how he phrases things when spoken aloud, highly influenced due to his career as a teacher. people will always be looking to him for answers, and he tries his best to provide them with confidence so they will 1) take his words to heart, but also 2) consider him reliable. because he wants to be able to support other people, and he's clearly very compassionate. even his questions are typically directed to hear out the other person's perspective. if he doesn't know something, he will of course need to ask, but typically he still prefers framing himself as someone who is knowledgeable. where even in that, he implicitly emphasizes the importance of listening to others to make sense of the world.
while he doesn't exactly try to completely conceal his past or his mistakes, because he understands he still needs to utilize them to connect with students to reassure them that he understands (like with nao), he is still disappointed if it seems that this is... all that someone sees within him. you see this especially with sara commenting that he's a good liar, along with how frantic he gets over the cigar/cigarette issue, that he feels he has a duty to uphold being a responsible teacher. but it's especially interesting seeing that even with people like kai and keiji prodding at him for this, he still typically denies himself that indulgence before other adults.
that reluctance is actually partially what has brought me to believe that he's a recovering addict. so alongside the teacher persona, which he easily grasps onto to excuse this, he could even be using that to kind of. conceal himself behind too. with keiji, and implied with nao, you see him mention how time is the only thing which helped him heal from the mistakes of his past -- and it could very well be that the solution he found at the end of that, to become a teacher, is the thing that truly pulled him out of that. perhaps privately, he still seems to associate himself as irresponsible when he doesn't have the weight of being a mentor. which is what leads him toward boasting such confidence, using white lies (i do feel like, bc of this, it was particularly significant for him to admit how much he still didn't know to kai), and doubting himself...
i do wonder how difficult the start of the school years always seems to be for him in this case. even if he knows it simply takes a while for the students to understand who he tries to be, it must be so stressful/demoralizing to bear that at the start of every year. but he does get back into the rhythm of things! he's very good with people... probably one of the most socially-adept people, up there with joe's skills.
it's funny that, even after going on about all this. i wouldn't consider either of them to be necessarily... insecure people. more than anything, i'd say that they're just. uncertain, and are scared to admit that. for kai, being uncertain is to proclaim that he isn't fully living, isn't cherishing that gift granted to him. for kazumi, it means admitting that for all he says, he doesn't have an answer for himself as to whether or not he can really accomplish what he's dedicated his life to after fumbling with it for much longer than the average person. they're both trying to understand where they go from here after practically... rebuilding themselves from the ground up. (kai with asunaro, of course; kazumi with the whole. ego death lol)
but when they look upon each other, they're still. very kind. and they offer what they believe the other wants or needs. there's a lot of trust between them, because they're trying to show that... it's safe to let those masks fall aside; that doing so won't mean losing the respect and love they'd want to harbor, things that feel as though they're at risk if they can't keep up appearances. but having that comfort with each other is really... special :']
