I dislike the "childhood friends, but one forgot and the other is mad about it to an irrational point" trope. I disliked it in Canno's manga, I dislike it here too. It feels petty and forced.
man these idiot couples T-T
Poor Hinori being the thirdwheel between them. I hope author will give you a gf unless ??
Call me crazy, but I think it would be even funnier if she was the only straight one surrounded by lesbians who are failing to arrange themselves into a functional configuration of couples.
I'd read a story like that, sounds entertaining if done right.
