Pfahahaha, I was literally just rereading this on Danbooru and popped open Dynasty to see if there was anything new. Glad to see it here, it's super cute.
My favorite part (besides Badass Meiling) was Flan. She obviously knew something was up and used her crayons as a sort of test and an excuse to get Sakuya to go out of the mansion.
I love this one, and the Sakuya story with the psychadelic oyster.
Btw this is the same author of Hakumei to Mikochi. Here's their site (looks like it hasn't been updated since '12 tho): http://musyaprune.web.fc2.com/
This is really making me want to see a manga series focusing on a cute kid whose parents are just quietly gay in the background. No fuss, no drama, just a cute slice-o-life setup.
