I suspect Kasane's Otaku Brain is going to be the main obstacle for them throughout this whole thing, judging by this chapter anyway.
Sure, yeah, "communication! Just talk to each other!" is good and important and all, but when one half of the main romance pair is stuck in the "glorifying the objectification of the abstract ideal that is yuri" and can't even parse the issues surrounding the ex-idol being in their house with just Meguru, without going Full "duhhrr yuri friendship" Face at the fantasy of it?
Good luck, Little Sister.
Anyway thanks for all the work catching up on the raws.
