Yeah, I’ll be honest. The smut tag doesn’t really apply to this manga. Sure, there is a lot of eroticism and explicit visuals, but the sexual themes mostly play off as gags and feel really playful and natural. This is mostly because Noda Satoru first and foremost emphasizes characterization and relatability. While there is a lot of objectifying of sexual attraction and physical touch, Noda reminds us that these people are human, and that sexuality and fetishism is only a small sliver of human nature. Also, the historical setting and universal acceptance by the characters of these themes really normalizes it (at least, in my opinion) to the point where the reader isn’t as fixated on these behaviors.
