So, as I had pointed out in numerous posts before, the way Daikenyako is framed - or rather Miyakensuke, to keep the correct yearning order -, is pretty damn insane to me.
I still haven't decided whether I find it "too simple" or "just right", because while the framing was incredibly obvious in my opinion, it was still done in a way that didn't feel overbearing. Not only did a big chunk of animation budget go into their scenes specifically, but the dynamics were also played rather consistently.
I had once made a "joke post", implying how the order of yearning basically goes like this: Miyako > Ken > Daisuke > Ramen. And while it was meant to be a joke... Upon rewatching it, it is rather accurate to be honest.
The main theme of these three is usually the following: Daisuke does something brash - like interrupting Miyako, screaming, complaining - OR something inspiring - like giving friendship speeches - and Ken and Miyako react to that in some way. Mostly verbally - but also through physical touch. Miyako and Daisuke have quite a bickering theme going on; Ken is usually softer, but he ALSO has more opportunities to touch Daisuke...
They are literally acting as his "voices of reason", who add to the discussion. In general, Miyako is very responsive to basically everything that Ken says and does, so she is almost always framed next to him - or at least close to him in some capacity. I will outline how Miyaken in particular is framed in another post, just know that she is very obviously and actively trying to reach out to Ken, calming him down, reassuring him, getting his attention.
That becomes even more blatant by the fact that she is getting in between Kensuke moments TWICE - usually to tell them to get their grip together or focus. Technically, this could be seen as her being well aware of how focused Ken is on Daisuke - and that a tiny bit of jealousy may have been involved here. On the other hand, she may just enjoy teasing him/them gently, because, "ya know how the boys are".
Either way, most of the time, whenever the group is together - and Daiken aren't off on their own with Rui -, Daisuke, Ken and Miyako will be together in the same frame 90% of the time.
It's interesting too, because Miyako - while obviously being more thought-driven in comparison to Daisuke's heart-driven actions- uses very similar terms to reach through to Ken. As mentioned, she is actively flirting with Ken through the course of the movie. And Ken, while being mostly oblivious to that - while still being thankful for the reassurance - is trying to reach through to Daisuke on his own behalf. (This is also very nicely framed visually by how much "hand on shoulder" moments there are, with Miyako being very inclined to touch Ken, whereas Ken - as mentioned - is very often seen touching Daisuke.)
Miyako herself notices how Ken had been flirting with Daisuke and acknowledges that by calling them out.
Who does not acknowledge it though? Right, Daisuke doesn't. Either because he simply isn't aware of the blatant flirting - or because he may or may not want to get in between.
I had already lost my mind in the cinema during one of the Miyaken focus moments in which Miyako told Ken that they shall not stop thinking and will find a solution - just to see Daisuke walking out of the frame.
One may argue that this means that Daisuke's true love simply is Ramen - as he keeps bringing it up time and time again -, or that he just wants to give the other two some space, as he may have felt like a third wheel before... Who knows.
To sum it up: I feel like the creators did a very interesting job here. Not only did they acknowledge and portray Kensuke's very ambiguously romantic-platonic relationship, but also committed to making Miyaken more obvious - a ship we know will end up together eventually, but hadn't gotten that much focus previously. Not to mention the blatant use of bisexual lighting here...
On a more light-hearted note: Ken is either caught in a bisexual triangle or we can just assume that this is a very fun depiction of a poly relationship in which all parties allow each other some space - or actively tease each other about it.
