I mean, yeah, the MC is completely useless, but it just feels like a lot of what Takane does is straight up counterproductive. She's explicitly said before that she's making moves and dropping hints in order to get him to go after her (when she was consulting with Eri), like dressing up in cosplay and whatnot, and in this chapter she's inviting him to have sex (albeit vaguely and indirectly). But then when he doesn't get it and she backpaddles, she says a lot of things to him that'll encourage him to continue to misunderstand her as well as make him afraid of drawing such conclusions in the future. Like hinting that she was setting him up with hidden cameras, etc. It's like, he's already dense as fuck and super insecure, and you are feeding into that all the time, making the likelihood that he'd take the initiative and do something proactive drop closer and closer to zero. Isn't that the opposite of what she'd want?
He's not even all that dense, he's just under a specific sort of impression about their "statuses" and her behaviour sends such mixed signals. He's still
somewhat dense, but really it's mostly on her with how she behaves. On one side, her body language and the degree of familiarity with which she treats him indicates interest (which I imagine his subconscious understands on some level, considering
his increasing familiarity), but on the other hand her
words completely throw off that impression. Worse, it's not straight up tsundere, it's a mixture of tsundere and oujodere, which blunts the "tsun" part by making it a status thing, which also results in making the "backwards affection" thing harder to notice. And worst of all, she can't even have those "moments of genuine praise/appreciation" since she
does give him genuine praise, she just covers it up by making it
appear negative (ex. in "he's become an irreplaceable part of seeing the first snowfall", the "the contrast" could alternatively be construed as the contrasting feelings of the crisp and cool beauty of the first snow, and the warmth of being together with the one you love).
On the other hand, she's at least able to be honest with
herself (and even others) about her feelings, she's just no good at telling the person who really matters (which I would assume is likely a matter of either excess pride or inadequate courage). I honestly figure this puts her at more of an advantage than most tsunderes. Personally, I consider being honest with oneself and cognizant of one's emotions is one of the most important skills that a person can have.
