Osoraku Kanojo wa Ore no Aniki wo Neratteru - Vol. 1 Ch. 7

[Kaarme]

Rei-sama isn't bothered by the small things, which girls find endearing. The MC eyes every woman like a mortal enemy, which most girls find not so attractive.

lol Rei being a bit of a slob at home is pretty hilarious. All these girls idolize him, but he ends up picking one and then they are like... holy shit... this guy is awful. Hahah. As for the class president... she's just another of the typical girls... not super into her really, but whatever. Also didn't help the whole chapter being about her instead of the main couple who are very cute.

Don't underestimate how willing people are (at least in the short term) to accept flaws in those they're sexually attracted to.
A 45 year old wife, 20 years into her marriage might riot over it but a single teenager? The dude's attractive enough to make it through any "bad second impression".

As for the president, it wouldn't surprise me if she (closely) observes the MC for long enough for shenanigans to happen and she switch her affections to him.

So glad the brother isn't an ass, i lowk saw it coming after he casually approached youta about bringing the wrong bento but this confirmation is nice and makes youta's lack of ill will towards his brother, make sense

Wow didnt expect to be so good.
Its hilarous, lovely and horrible at the same time. Might be the perfect romcom!

Wonder when the author switched from shoujo to shounen, was it because of local reader feedback?
I like that, I don’t want a love polygon drama with the older brother

Edit:
To be clear, as far as I know most shoujo manga have more than 1 guy falling for the FMC (reverse harem). As someone with double standards, I dont like that (harem is fine tho =)).

I used to not care about Demographics, but I've watched a very famous anime, Maid Sama and there was a scene that a jerk-fuckboy tried to rape the FMC. That scene made me feel this ain’t it. Then I checked manga spoilers and found out the jerk was whitewashed and successfully force-kiss her in front of the MC even though FMC-MC were already a couple. Whats worse, some girls in comment showing their affection for that jerk. WTF??

Later I watched A Sign of Affection and dropped after 2 eps. I realized that hard for me to watch shoujo manga/anime, unless there's only 1 MC-FMC.

Back to this manga, if its still shoujo, I bet 90% the older brother will fall for the FMC and love polygon drama will happen. If thats the case, I think I may drop it

That's not how demographic works

Also you seem to be the guy that wouldn't mind if the genders were reversed 2+ girls and 1 guy

Finally we Will see the brother but danm with How Crazy those girls are MC actions are starting to make more Sense

Yep, he deals with them on a DAILY basis btw. It just isn't shown since the main focus are the cute and funny moments of FMC and MC.
He's relatable for me since I've been in the same boat (without Houjou ofc)
