Was nice to kill time but eh, defo could have expanded more on the actual West vs. Touwa conflict, more focus on the side-characters that didn't revolve around Inuzuka(We barely got anything on the 3rd year prefects, wtf even happened to Scott?), maybe could have gone as a more explicit battle manga considering everyone seemed to have superhuman strength for some reason (I think this is what the author was going for with the mention of 'alchemy' in one of the early chapters but then decided to abandon it?)
Also, I probably shouldn't expect top notch political drama from a fluffy romcom, but all the difficulties involved in the forbidden relationship are very conveniently solved by having a literal princess bail them out. Not to mention that the change in the West-Touwa relations rippled downwards from the aristocrats, with normal people presented as hateful racists which could have been handled alot more gracefully. Like, the war had been over for decades, the regular people don't really have actual beef with the Touwans.
Also, anytime the mangaka had an actual interesting choice for the MCs to make, he basically gives them an easy way out (Like when Inuzukas and Juliet's relationship is revealed by Leon) Let them struggle, let them get expelled, confront their ugly political reality directly.
The White Cats and Black Dogs also had a 'frenemy' vibe from the start. IMO, there should be real reasons for the hate between them. It'd probably make this manga too dark if it had more realistic and less goofy violence though. (Like Maru and his crew in chapter 1 and his box cutter knife slicing up Juliet's clothes.)
To be fair, the scale of the Touwa-West conflict is global, so there wasn't likely to be any 'clean' way to wrap the story up. Maybe if the mangaka made Touwa-West relationships frowned upon, but not like something that would ruin your whole life. I guess that'd also take away alot of the gravity of what Inuzuka and Juliet are doing in their world, but it could just be a jumping off point into exploring the wider Touwa vs. West conflict and its consequences. (e.g. Why are there Touwa 'radicals' on Dahlia that want to kidnap the princess, what's their motive? Since they're presumably not government forces, why are there Touwa paramilitaries just lurking around? EXPLORE THIS)
