I have like zero faith in the survivability of poly relationships but still, gotta say I was a bit disappointed
Like, they even brought up that concept up as a viable option, what with the nurse and her two amigas and all
What the fuck was up with that?
People seem to gloss over the fact that a basic premise of the series is that Mei has been somewhat traumatized by her ability to see the pink arrows of love, and she starts out wanting to have nothing to do with romance for herself. So a lot of the series amounts to Mei, in effect, shopping around various types of love until she finds one that suits her.
So to some extent the poly trio is just one more kind of love that she learns about rather than necessarily a plot flag indicating what the series endgame is going to be.
I don’t deny that the possibility of a poly ending was hinted at here, so maybe this isn’t the precise place to mention it, but I do think it’s striking that in the Dynasty forums not so long ago every time a third party was on the scene in a series a number of readers would automatically lament at the start, “Oh, no—I hate love triangles! Yuck! NTR!” But now it’s, “Maybe it’ll be poly! It should be poly! It must be poly!”, with everybody lamenting at the other end if it’s not.
