After 11 years, it seems the misunderstanding that started this all has been revealed (to Hayate). The first couiple of pages were a bit saddening for me for some reason (mainly because the long-running manga is directly referencing HnG as we all know. probably.)
I wonder if this would be the main theme of the final(?) arc? I also have a feeling like some of the people here that it might be the cause for that negative emotion needed to open the Royal Palace.
