I dunno, it's kinda weird. And unfortunately I think it has just one more chapter - in Hirari 13 - but please do correct me on that point if I'm mistaken.
The part with the bomb was really funny and cute though.
There seems to be more from what I saw on the artist pixiv so we might yet get more chapters, maybe at least 3 chapters or more
I literally just saw the article on Crunchyroll, and my thought was "Wait, doesn't this look familiar? Maybe something on Dynasty Reader?" Although the name here is different.
