So like, is this just going to be an allegory for societal roles? Thats kinda boring.

No exploration of the inner workings of the world? Idk, it feels...
lazy? Not sure if that's the right word, but you get what I mean, right?
Hopefully the manga actually explores the inner workings of this world in future chapters, and it isn't just replacing societal roles with romcom ones. It's kinda lame to make this manga
just an equivalent of "we live in a society."
The moral itself isn't
bad, it's just
common. Maybe it'll get more fleshed out, probably hopefully maybe idk.
It's probably still too early to be making these judgements tho, so I'll let the mangaka cook a bit more before coming to a definitive conclusion.
As for the rival character, I think he's neat. An alright subversion of the trope, I suppose. Not much to say on this end.
