I thought this manga would take a mature approach at capitalism, ecology etc but it actually just doesn't. The first act did raise the question on how to deal with the powerful that exploit the rest of the world, but the answer was just "we'll revive them with science and make a better world with science and science science science". It is getting less and less serious as time goes and I'm starting to wonder what I liked when reading this.
Yn-hi is so passive it's annoying . Maybe for a japanese audience the trope "get's taken and is too afraid to say anything or complain" is somewhat romantic but that's not doing it for me.
agreed
It's not romantic but reasonable
It's not meant to be romantic, in a sense. She certainly doesn't seem taken by him, but she is overwhelmed by the city and finding out that she's now with the prince. But since we know how these two end up, odds are it's going to be their interactions going forward that will be romantic. So the trope here is the whole "I can't stand you, but eventually I will love you" kind of thing.
