That’s the joke. The whole schtick of this series. It’s SUPPOSED TO BE DUMB AND GOOFY. It reminds me a lot of an inverse version of that “You’re Totally in Love With Me, Aren’t You?” manga where it’s just as goofy and the whole joke each time is the MC asking her friend who’s obviously crushing on her if she loves her and the friend always denying it. I think the only reason people are fine with that one and bash this one is cuz this manga has a more realistic art style and isn’t in 4-Koma style, so subconsciously think it’s supposed to be a realistic drama and not a silly comedy.
Maybe this isn’t your brand of comedy or whatever, but that doesn’t mean it sucks. It’s actually doing what it set out to do quite well.
Whatever, you can say it's supposed to be like this, "dumb and goofy", only problem is it is not like that, I would say it's "senseless" more than dumb, she's just making unrealistic excuses that no one, not even the most oblivious person would think, and "frustrating" more than goofy, because up till now, or at least in the latest chapters it hasn't been funny at all.
And it's nothing to do with my "brand of comedy", I actually quite like this type of manga, for instance another one that uses this same type of dynamic and is being uploaded right now in the site is shoujo manga protag X rival and guess what, it's pretty funny and I like it a lot.
Another thing to add to the senseless of the story, and someone else pointed before, she's supposed to be a "former womanizer" or "woman eater" or whatever, but how come when she can't get these obvious signals? Or what, you expect me to think every girl she hit on wore a shirt saying "I'm a lesbian"? or the rainbow flag or was registered in the national lesbian catalogue or something? IT DOESN'T MAKE ANY SENSE, like most of this manga, but the main point is, it's not funny, because there's a lot of things in shoujo protag X rival that are senseless too, but at least they're funny, this is just stupid
