So he got sweaty (from, what, PE?) and somehow she knows this and can somehow smell him from feet away? Then she starts comparing him to some guy that practices basic hygiene (...let's leave aside the very questionable bit where she knows what he does in the bathroom somehow) and is overly concerned with his appearance and suggests he does that? Doesn't this kind of conflict with that past "have more self-esteem" bit? I mean, it'd be one thing if his hygiene was legitimately bad. But it isn't. And while human sweat does smell, it's also rather fucking difficult to smell it from feet away unless it's old and used clothing (which, admittedly, can smell terrible, depending, and from a slight distance at that), so it's questionable how the fuck she even smelled him to begin with.
This girl really grates me for some reason. Mainly because her entire character is based around trying to be a "helpful" "older sister" like character that helps with his "personality flaws" while having a myriad of her own.
It's also interesting, because the last chapter with the dream actually had substance and depth to it instead of... this low effort shit... where it's like what a program that interacts with humans would think humans would say. I thought the manga might potentially start finding itself, gaining a teensy-weensy bit of self-awareness (and not in the ironic sense) and actually try for something substantive. Apparently I was wrong. For instance, just having a SINGLE PANEL where she blushes and thinks something like, "Phew, that was close. He smells so good! ...Wait, no, that's not what I meant!." or something like that... would do fucking wonders to improve this shitshow of a manga. But the mangaka can't even fucking do that.
