I like so many of the tropes here. (long lost childhood friends to lovers? yes please. A bad boy falls in love hard with a sweet uke? Yes Please. Size differences? YES PLEASE.) Because of that, I sure am willing to overlook how dated the story is. The plots are really relics of its time, from back when I first read it many years ago. The conflicts, the misunderstanding, all of them feels stale by now. Given how Natsumizu Ritsu's stories can be, I'm just glad that this one story doesn't employ SA. That sure will make the plot even more outdated. Characters are pretty okay. They're archetypalsure, but again, I do like them. And this story employs them properly.

This story also looks at the host world with a more cynical, misogynistic attitude. It makes sense given the background of the character involved, but I can see people flinching at it.

So I think how you like this at present is highly dependent on how much you enjoy the basic premise.
