All those tests to study his magic level when they could have simply made the paper only visible to someone of their preferred magic rank. That seems less problematic all things considered. I mean, how is someone going to explain a rank 2 magic user being unable to walk into a building? Overall, looks like a decent start.
@twinklecake Honestly I think the answer is literally "Because Japan" as it is a culture where compliments are usually pretty formal at most to strangers. So saying that someone is "cute" is enough to elicit some reaction. Same thing with walking hand in hand in public, Japan isn't used to it yet so men and women tend to be embarrassed about it whereas in other countries it's just kinda expected. So I don't think it's meant to represent a cuteness, per say, but just representative of their own culture. They seem to be somewhat aware of the awkwardness of it, but not many of them really wanna do anything about it so they just go with the flow.
