I don't think the author is making any mistake or doing anything unconsciously. The opening lines of the story in the first chapter are, "Fashion magazines are my textbooks. They say that, if I dress up, put on makeup, and find love, then even someone like me, who's subpar in every way, can be normal."
Given the way it is framed, with Hinako looking depressed at the same time, it seems pretty clear that the author is well aware of the way media for women tries to undermine their self-esteem to sell them products. The idea of getting a boyfriend in order to be normal is a recurring theme in the story, and showed up in the previous chapter too.
So far, this story seems like a deliberate critique of the subcultures you suspect the author is leaking unintentionally.
