Keltham needs a Plan.
He needs to handle this attempted mass mating rush in a way that neither immediately escalates to cuddling, nor signals that he is opposed to the mass mating per se.
Can he just... be nice and smile at the girls, but pretend not to notice their flirting attempts, for now, possibly? Or be deliberately ambiguous, leaning negative, but with occasional positive signs thrown in? Would that work to correctly signal that he was delaying but leaving his options open, if the underlying strategy was successfully decoded by the other side? It's more of a classically feminine stratagem than a classically masculine one, obviously; but 'feminine' is here standing in for the sexuality in relatively greater demand, and the inversion for his own case should be as obvious to them as it is to him. And even if the stratagem isn't correctly decoded by the amorous horde, obscured by unknown subgaps of the cultural gap between he and they, it seems relatively failsafe? Given the common-knowledge-avoidance underlying theory of flirting, sending ambiguous-leaning-negative signals should avoid either escalating or terminating -
Wait. That style of flirting exists in dath ilan, deployed by people who know what 'common knowledge' is. It's not a very advanced formalism, but it is very plausibly not something that exists here, or that exists but is beyond the lower quartile of a population with -3.2 average intelligence.
A lot of romantic complications seem like they would plausibly be beyond the lower quartile of a -3.2g world, if that world designed or just equilibrated to romantic systems that worked for almost-everyone.
...do amorous girls in Cheliax... even do subtlety... at all...?
