Neko x Neko
Seke couple They're kind of weird and annoying about it at first - The smaller, younger, more "cute" of the two is initially the uke, but over time he grows taller and more muscular, so they initially present everything as "well yeah, since he's bigger and more 'manly' now, I guess he's the seme so they've got to reverse roles! No other choice! Doesn't matter that the older guy doesn't like the idea! And I guess this is just how it'll be, now! The younger guy who liked bottoming before will just never do it again, because he's bigger now and those are the rules" and there's also a bit of transitional "the guy who wants to top is the one that wants to have sex. The uke just puts up with it" sort of stuff and a bit of an allusion to the idea that the older guy "has never really been gay, he only wants to sleep with the uke" which adds a smidge to their "drama" about him needing to give in and bottom. There's quite a bit of transition. But once they sort of get over that, the relationship between them is quite sweet. And they start switching a bunch more, and even have some more realistic observations about their dynamic (the older guy has a moment where he realizes he doesn't want people to think he's a bottom, because it will make him feel like less of a man, and at another time the couple talks about how they both "feel it more" when they have sex a particular way). All in all, it's a sweet couple, and definitely tries to break away from some tropes, even when it seems to reinforce them just so they can break them a bit later

So in both cases their relationship starts out problematically, and then they essentially become the most codependent ever. Every single thing becomes a threat to their relationship that must be surmounted. And every antagonist looks exactly the same, which is hard to keep track of and I don't understand the motive of the evil prince. But the MCs are ridiculously devoted to each other, which is sweet, so I'd call it quite romantic
