Ravenclaws tend to be the auspistice in three-way relationships, though it's probably more of a duty than desire. They're rational enough to know that there needs to be balance and they're level-headed (not to mention prideful) enough to want to take the responsibility.

That leaves the redrom majority for Gryffindors, but oddly they tend to have equal numbers of blackrom for reasons they can't quite figure out. (Everybody else knows it's because they're brash and in-your-face and get on people's nerves, but they think they've got the flushed romance quadrant locked.)

The school dances may need to be more specialized. The dueling club is considered a romantic pastime for blackrom couples, much to the annoyance of people who actually want to duel and who come out looking like sweethearts. Nobody talks about its impact on Quidditch matches by silent agreement, especially since some of the Gryffindor/Slytherin matches almost wind up porny. (Harry/Draco shippers rejoice!)


Trying to stay away from characters, but I've got to say that Harry must have had some very confusing black feelings growing up, since Snape had to tone down the abject hatred and abuse or risk looking like a child molester, which only made him hate Harry more. And since Harry hates him already, and keeps being antagonized, but not to the point of actual fulfillment of black feeling, it must have spilled over into his relationship with Draco, which probably may have caused him to either come on too strong sometimes, or rush certain parts of their relationship. *coughwildbackcorridormonkeysexcough*
