I wasn't planning on doing a review of this manga but when I saw earlier today that Kanojo mo Kanojo was getting an anime adaptation in 2021, I jumped on MyAnimeList.
I really hate how these kind of mangas can be adapted so easily. The manga literally started on March 2020, it just took 6 months and 35 chapters to get an anime. Damn.

Bear in my mind, I don't actually dislike harem, or just romcom in general, even if they are kinda bad, I just need some enjoyment to read it casually when a new chapter comes out, or at least a good waifu to cheer for. There's nothing to like in Kanojo mo Kanojo in my opinion, literally nothing. I don't know why I needed 23 chapters to drop this massive disgusting manga.

All the characters are obviously generics but they all feel so empty. The MC is just a dumb screaming person, all the girls are nowhere near interesting.

Harem manga is nothing new, a lot of them are at least decent to read. If you really are a big fan of the genre, maybe you will like this one but if it's not your damn dream, you're just gonna hate this one.

Just don't read it.
