Fully trained on both solo pictures and couple pictures, Flux can use this LoRA to readily generate them individually using their own trigger words (although Kendra seems to have a slightly higher hit rate than Hailee).

As for generating couple images, I'm running into the standard Flux / SD problems with these, it's very hit and miss and there's bleed of features between them.

I'm sure if you can use Regional Prompting or Inpainting better than me (or you're a Comfy user aka "Spaghetti Wrangler") then you shouldn't have any problems.
