I thought it was too early to make a comment on this series but people are really jumping the gun, and it could go in either direction. My experience is the opposite. I read it because of the mystery, just had to find out what it was. But it was lame. It really had nothing to with the character we were following and it would have basically belonged in some other manga. By chapter 2 it's explained that this is a manga about two people that accidentally ended up making themselves isolated from dealing with the opposite gender. It's a bit of a farce. The guy's situation is more properly explained while the girls is glossed over so far. Though his is far more unlikely, also another manga using gynophobia(well a anxiety akin to it).
Mein is being quite insulting, which isn't to say he shouldn't find something boring. But I do understand what he says, the manga says the protag has good social skills but starts to lose it when women are forward(putting their bodies against his ect). Are these two character traits contradictory, unlikely maybe but I don't think think they contradict, and I don't think getting nervous over holding hands is unfathomable either. These two people have a severe anxiety for a very specific thing and they're working on it. They just both want someone that goes at their pace. The twist in the beginning is something that pops up nowadays, and I think it'll pop up again with the second love interest but I don't think it adds anything to this type of story(instead it'll end that plot thread) or maybe not, it could be the thing that pushes duo together(I don't know but otoko no musume has burnt me on mangaka thinking they're clever with wannabe shocking twists in manga that don't call for it). If they don't both make a choice about actively choosing each other and there's no one else, it's a bit like settling while he says he likes someone else.
This isn't for everyone though. If you can't relate to the joke or sentiment of admiring someone that you're gay for them while being straight, then you really won't like this(I'm phrasing it like this to avoid spoilers). Those who don't understand that might even find it offensive.
Also, the other twist this manga has is another that's popping up. The guy is called beautiful though often times these types look about the same as any random manga protag. Women like him and that's a thing, early on they get a good joke out of it by having him just be depressed and it coming out off like the type of thing that makes girls swoon(think zuko on the beach episode).
The humour is okay, there's usually a few good jokes peppered around(even one on the title that I was thinking the same thing on, "isn't that just regular friends"). But you're face, stomach, lungs ect won't be hurting.
