I wanna like this, but the gag is too thin. I mean really, for him to still be semi-scared of her after all these chapters of her being so good to him except for a bit of tsundere requires more than just dense, it requires subhuman stupidity levels. So every time the gag gets looped again it's less and less funny, more and more frustrating, and less and less believable unless our MC's name is Forrest Gump. But in this kind of manga they basically have to keep on re-treading it no matter how stupid it gets because nothing much can happen until the final few chapters, whenever those turn out to be.
So yeah. I rather like her, but the manga as manga is just too boring and annoying. (And it is in no way a contender to Komi-san, which has a ton of good jokes not just one stale one)
