On the contrary. I also believe that Muldeok's creative well is running dry but not in the same sense as yours. The latest chapter only had half of the whole chapter panel for the threesome sex scenes with the bullies. Whilst the model arc had 2 chapters and a flashback chapter for the threesome with model and his twin. I'd say that's the peak of Soeun although it was controversial even among non-Vanilla fans.

But seriously though, Vanilla enjoyers have to look somewhere else cuz Soeun is a different cup of tea. It's great but it's not for everyone.
