God this need like an idiot couple squared tag
They're not stupid, they're both in denial (and tsundere).
The Idiot Couple tag isn’t about the overall intellectual capacity of the characters; it’s about their inability or refusal to see that they are a couple, or at least that they are emotionally attached in ways that they can’t or won’t admit to.
While there are other ways for characters to be an idiot couple beyond overt denial or being a tsundere, those are certainly two standard ways of getting there.
This is definitely what I meant.
But the denial of feelings and the possibility of being together is a huge staple of the romance genre. If the idea is to add Idiot Couple simply because it would look funny then I guess it doesn't matter, but if it is to be useful then it can't be added on just any random series where the characters are not honest with themselves.
Dynasty currently seems to use it only on comedy and slice of life series, which implies that there is an inherent silliness to the concept. Meanwhile one of the quirks of this series is that it plays very little of the central dynamic for comedy in the typical sense. (It is often funny, but the humor is so dry it's usually hard to tell if a joke was meant to be a joke.)
