My bets are on a Valentines release and it includes reworks and extra content for the romance route ❤️

Not used Fooocus but yeah pretty much the same output can be generated with the same models and settings, you are just swapping the interface used;

So your only real step for producing something like the above with Fooocus is to get the Plant Milk Model (Stable Diffusion XL (SDXL) model) installed this can be found on Diffus and adding it to the \Fooocus\models folder.
Steps to Install and Use the Model:
Plant Milk model file (typically .safetensors or .ckpt) downloaded.
\Fooocus\models\checkpoints
Plant Milk checkpoint file into this folder.

IMO - Stability Matrix is a lot less complicated than what Fooocus appears to be outside the standard UI. With SM you can download/install the your interfaces and models directly from SM and then the interface within SM is more than useable without the need to to use a web browser application.

Download/Install Stability Matrix
Download/Install ComfyUI from Packages in Stability Matrix

Thank you very much for your reply. But, as I mentioned above, I'm having problems downloading packages. The program itself downloads, but then the packages aren't there. It always gets to "Python download complete" and that's it, the program kind of freezes and doesn't respond. When I close it and try to download the package again, an error message appears. That's why I asked about Fooocus.
