I 100% love how the manga commits on the portrayal of Makino as this flawed character that made and still makes a lot of mistakes and doesn't instantly get changed, that would be the lame easy way that the story could go for a russhed ending or development.
Sure, a lot of the things that happened ever since Kosuzume's decide to introduce Mashiro having depressive self doubt thoughts made a lot of people rightfully confused as to how Makino managed to still seem like she "didn't care about anything but fluff", but for me that's the best part, Makino stayed true to previously written actions.
It is very clear to me that Makino messes up by intentional design of the story, even weird plot tangents like Rina-Rina and how Makino's sister got blackmailed are in line with how Makino was set as, quite literally, a Scumbag.
I really love how this manga portrays sensible topics, it's between a lot of fluff so it comes as unnatural for some, but for me that's a way better way to ease the stress or problematics that they could bring
Anyways I overanalyzed this a lot sure but I think this manga is worthy of doing that
