"Cheating is good" is definitely not the lesson I learned here. It's nuanced in the sense that not everyone can and will do the things we as audiences want them to do, like couple's therapy or even just talking it out.
So far I'm liking Ichinose's combo of aloof gyaru, gap tsundere, and baseball otaku, and Nagisa's signature Yamamoto charm.
But honestly, everybody's top tier in this manga. Get this a quality anime adaptation and inject this to my veins.
I agree with for the most part except Kusunoki being a simplistic one-dimensional cardboard portrayal. Based on previous dialog it seems she has other personal issues that haven't been shown in the narrative yet, which makes her a compelling character to me.
