Ayyy I kinda sorta not-exactly-but-close-enough called it way back. Either case I love that she's noticed her before and was drawn to her as well, gives her impish/seductive/horny-on-main-seeming behavior some more depth and it makes a lot more sense. Big fan of this development.
As an aside, for some reason, in my mind, I almost expected Meguru to proclaim in a The Exorcist-esque demonic possession horror movie style that "the sow is mine" to her co-worker. Not going to lie, would probably love this sort of twist.
