I will say, to those hoping the other oneshots get serialized, it's highly unlikely. This particular oneshot was unique out of all 3 volumes of oneshots because it was purely based on the original cover art drawn by maro and did NOT come from a previous written short story on syosetu (every single other one did, even flowery path of evil's sequel). For any more to get serialized, the original author on syosetu would have had to have turned their short story into a web novel series.
