God, this is so adorable. I really hope the author continues it and the "The end(?)" is just a false alarm. Thanks a lot @G-P for the work, I love this manga.
@zetsuravez it seems like the blonde girl is just another recurring character from the author's twitter. The cover is not really an official cover since there doesn't seem to be one. It's just a piece of art the author made. Blondie is probably not related to the series at all.
@Orpheus2020
The last panel of this chapter on the author's Twitter does say おわり which means 'End'. What G-P added was the "(?)" after "The End".
FYI everyone, unless you can communicate in Japanese, even if it is broken, please do not pester the author since they are most likely working on multiple projects, and they are very likely to not be fluent in any language other than Japanese, so bugging the author about this would only stress them out, especially if it is in a language they don't understand since they would feel obligated to respond. Your consideration would be much appreciated.
