Your criticism is "why isn't the author doing their story the way I want it" which seems to become a increasing trend among manga readers these days, in both the professional and amateur areas.
God forbid people discuss what they like or dislike about a series or a specific chapter/arc/character/etc., in a manga forum of all places! It's not like criticism is also part of loving and enjoying a series, and being a passionate fan (complaining is also fun tbh)!
No, my criticism is the author hooked (most of) us with the slice-of-life monstergirlfriend experience, but the people who were reading for that got bait-and-switched with a shonen manga genre shift out of nowhere when the series is almost over. Do they not matter when (I assume) they are most of the fanbase?
Nothing wrong with baiting us in with monstergirl cake, but there was zero indication they were eventually going to fight a literal god since the series started out, and a majority of it, is slice-of-life/romance. I did not read this for the action or worldbuilding because I'll just read an actual shonen series for that.
Still, the essence of my complaint is the shonen genre shift came in super late. I probably would not have minded it if it came early on, instead of when the story is basically over at this point.
Also putting "lol" doesn't automatically mean you're joking. It just means you're laughing, which can be in a light-hearted, mocking, or mean spirited manner. That's the reason why most public forums unofficially use /jk to indicate a joke, or /s to indicate sarcasm.
Okay forgive me if I'm been "lol" using it wrong... this has been, well, the only forum I actually use. But it also seems to me that /jk is similarly used to "lol", and heck, could even be interpreted as more sarcastic than "lol" in my opinion.
I also admit I've been overusing lol a bit lately. Might be time to taper it down lo-. Ehem.
