That is a pretty good point. If we think about relationships like in lawful/chaos, it just opens a new world of opportunities.
Lawful relationships would be an established monogamy or poligamy relationship, where each partner would only have a romantic/sexual relationship with their significant other(s).
While Chaotic Relationships would be something of an open relationship. Where it doesn’t matter if one partner does have sexual encounters outside the relationship, as long as it is established that the couple has a romantic one.
(I swear to god if I don’t find a thesis paper on the merits of love between alignments, quadrants, or every other idea of love that I have discovered from doing this blog, then I am going to fucking write one myself.)
