Love this story soju! When I read it I always thing of the stars as those treasured secrets you share with a loved one, so I think this would be perfect for the RE: Secrets collab (or is that just my interpretation?)
When I read this, first thing that came on my mind was this: Paper covered with thick coat of black tempera (with just a little water added to tempera, so that brush strokes are visible and tangible/pointed out) and when it is dried just sprinkle dust over it (dust from the ground). Or for more "fancy" version sprikle with silver make up loose pigments. Apologies for my really poor English :)
I love this tiny story! I want to see illustrations. Not having any drawing skill whatsoever kills me every time this happens. That's a lot of deaths, I'll have you know. :D
