On one hand, I wouldn't be foolish enough to think this is progress.
However I will say that, unlike older chapters where she asked herself if she LIKED Bakazuya, now she's asking if she wants to DATE him. It's not progress, but it's more than nothing, too.
She's turned down EVERY guy who asked her our that we've seen, so it's a big deal for her to consider anyone as a potential partner actively, much less Kazuya.
Still want to see Kazuya's mind explode during the lewd bits, saying junk like "Her breasts are like milky mochi!" or other delusional B.S.
