Awww...Kumichou really have a special thing for Dia, just like Pito with Kanan <3 that said, somehow i wish this would be longer XD i really enjoyed anything with Dia my best girl! Im rewatching LLSunshine again during this lockdown and i cannot helped but to notice how well Dia plays the strong japanese wife archetype, like giving her full support to Kanan in order to hide the truth from Mari and even willing to be the "bad guy" for her sake.
Thank you for translating this, too bad we didnt get to see Kanan and Mari's reactions though (about knowing Dia's mahoushoujo secret XD ) I really love how Kumichou made Kurosawa-mama a repeat appearance in most of Dia centered doujin <3
