Such an abrupt ending... I wouldnt be surprised if the author simply grew bored with this or felt too stressed to continue. Although I like this series, maybe it was for the better that they decided to quit here since their new manga Ikoku Nikki feels like it has more potential. The romance tag should probably be removed too.
I started reading this many years ago, and paused it to wait for the translations to be done so I could read it in one go (I tend to forget many things over time). Thanks for translating the whole series!
These extras were fun. The part with Haba and Kakei was too real haha
