The art overall was pretty strong, with only a few instances of the Sanada character looking very odd. I felt like it really matched the tone of the story overall.

Gender, as sadly usual, is a strictly binary affair. That said we do touch on either end of the binary and the representation of gay characters in Japan was very interesting.
Not historically a huge fan of BL, I am trying to dip my toes in whenever I come across something that interests me. I've certainly read more then enough slow realization of attraction stories from a hetero perspective to fill another two lifetimes, but as someone who was a repressed queer kid growing up, I'll probably never get tired of stories like this. What can I say, it's a bias.

Not a huge fan of this sort of age gap (for any gender combination), it's persistence of this character throughout the series was not surprising but kind of annoying.

As with most manga race is not touched upon at all in this series. Class and ability and disability is similarly overlooked.
