So right off the bat, the whole concept of a harem of brothers is a little... weird to say the least. Even though the characters aren't biologically related, it's still a little uncomfortable to watch. I think the concept of an only child suddenly being thrown into a huge family with a ton of siblings is a cool idea for anime, but I wouldn't make it a harem anime lol.
Anyways, if the pseudo-incest doesn't bother you, then the story and character development certainly will. If you don't know, Brothers Conflict was a light novel series and an otome game first before it was an anime, and I could definitely tell. The story (or lack thereof) was all over the place. So many plot points are introduced and either not concluded or concluded poorly. The characters are very shallow with little or zero development. The bully, the tsundere, the playboy... these characters' personalities are never developed beyond that. Some characters are even just neglected completely. I'd say this is because there's way too many "competitors" and not enough episodes.
BroCon also falls into the one reverse harem trope that I absolutely haaaaaate. Not only is the protag (Ema) bland just like the rest of the cast, but she just lets herself get pushed around. A reverse harem protag doesn't have to be a tough feminist or anything, but I would've appreciated it if Ema at least learned to stand up for herself or SOMETHING.
I don't really have anything to positive to say about this. The best aspects of it I can only describe as "it could've been worse". The art is cute, but all the characters suffer from same face syndrome. The idea's interesting, but it's executed poorly.
All in all, this anime was a bad attempt at cramming an entire otome game into a 12 episode series. It's not funny bad or entertaining in a corny way, it's just boring. I'd say if you're really interested in a sibling reverse harem, I'd look into reading the novels or playing the game instead.
