I agree (in general) with what you wrote, but it could work in the real world, where a loving couple practices BDSM, with predetermined rules of behaviour and delegating responsibility to the dominant for how the submissive will feel. It's all true, yes, it's a psychological thing, there's no question about it.I was getting ready to write the traditional wall of text, but I'll save both yours and my time and just quote the author.
Really, the wall of text hasn't gone anywhere, except shorter..)
In KG, most relationships are hypertrophied and there is not even a whiff of the famous "safe, sane and consensual". Moreover, I think that in KaneDom relationships, too, it's worth separating a truly romantic relationship from simple kink sex. There's no romance in fucking some a defenceless slave Amy with her head pressed to the floor because she didn't choose that fate and we're just taking advantage of her because we can. So if we talk about romance in KG, in my opinion (from the dominant's point of view), it's quite little and that's why it's more valuable, because in all other cases (at least at the current moment of time) it's just sex.
The only real romantic paths I see so far are between KaneDom+Veronica and KaneDom+Junko (love). Both paths have beautiful romantic scenes, both paths have the prospect of a relationship developing. Both paths demonstrate an emotional connection between the partners, especially in Veronica's case. There might be something similar between KaneDom and Olivia if Tess prefers the slow burn rather than forcing the relationship. Everything else, well, I wouldn't call it romance (neither with Dominique nor even more so with Juliette). Maybe in the future, if/when we see the development of KaneDom & good Dominique, something will change, but for now there is no special romance in their relationship (imo).
Alessandra - well you could manoeuvre here, but her "sub in the bedroom and dominant in public" requirements are very specific and unlikely to suit pure doms. And although my KaneDom is developing a relationship with her and her girl mate, there's no romance involved - it's more like fuck buddies with various perversions with no further romantic prospects. Maybe the subs have these rare romances too (as in the case of relationship of KaneDom+Veronica and KD+Junko), but only the subs can know about that, so if they have it, well, then those guys are lucky too.
To summarise, I'll say the following. Real romance is not born (imo) in BDSM relationships, but just the opposite - BDSM relationships between partners who already love each other are an additional layer of relationship development, expanding the boundaries of permissible and the degree of deepest trust in each other. I.e. BDSM (imo) is not the root cause, but a consequence of the fact that people love each other enough to trust each other even more in role-playing games of power exchange.
