Honestly, i also wanna know why the yuri tag is missing. "girl is pining for another girl for seven chapters straight" would normally be tagged as yuri. is it because the other girl's feelings are ambiguous?

Also, speaking of out-of-place tags, who is bisexual in this story? I don't think it's Hiro (seems to be laser-focused on girls - or rather, one girl in particular), not Karin (we don't know what she's into either way), and though it's tempting to think that Yukio and Hiro's dad are basically married, I don't think we get confirmation either way :)

I have to contradict the translators notes here, so pardon me.
I don't know much about the historic costs of Japanese foods and staple crops, but Mitsu specifically mentions that here husband "died in the war with Russia". The only war with Russia I am aware of Japan engaging in during the Meiji period would've been the 1904-1905 Russo-Japanese War, which would place the story as set somewhere around 1905-1906, most likely, rather than 1875 as the translator surmises.
Not that any of that has a huge impact, but my tism demands I point it out

I do like the translator's idea tho. "The author might have misplaced when the Russo-Japanese war was, but obviously they had historical soba prices on lock. Everyone knows those."

Ch5 100% convinced me that the endgame here is for the student and teacher to end up in a relationship (the fact that the author already made a student x teacher doujin is a hint as well).

The way that Nami is positioned here is hinting at a bigger rot in their relationship - that Kaede's just really a convenient girlfriend for her to have, but she won't fight for the relationship in any meaningful way. The blushing reaction Kaede had to the kiss proposition, and the way Nakahashi diagnosed the problem (i.e. she'd be inclined if Nami wasn't in the picture?) at least indicates that Nakahashi got under her skin too. The hand on the cover is probably also Nakahashi's.

Really unfortunate if i'm right, because i love the art style and how the narrative is told, but narratives portraying student-teacher relationships positively are poison, and I don't think this is angling for a realistic portrait of grooming.
