After consistently reading this for about 37 chapters now, I do somewhat agree with BluePhentagram in regards to the genericness of the setting (asking for higher class wars and acts of xenophobia for a series that's mainly lighthearted is a bit much, though). There isn't really anything setting Dahlia apart from school settings in general, let alone ones in romcoms, and while we do get nuggets of info about Touwa's culture, we're given very little knowledge as to what exactly are the West's customs beyond Persia's family (and at the point of writing this, even THAT isn't much detailed aside from her history with her father and Char). While this is ultimately moreso character-driven than something that focuses heavily on the general world and events, it definitely stings we never get any REAL in-depth reason as to why exactly the two houses act this way through side stories and the like.
That being said, I do think everything else about this - especially the art and shot composition - more than carry this. I don't even mind how Inuzuka's main focal point is his large affection for Persia, cause it makes for a good wheel of development on how to become a better person for not only Persia, but his own sake as well. Also, if I was able to read this for 37 onward non-stop regardless, that should mean something, right?
EDIT: Finished it in a single day, very much loved it. I still think it has some flaws, but again, everything else makes up for this. Inuzuka's a fantastic protagonist as well
