Characters from anime series The Apothecary Diaries. A winning bounty brought to you by @TRDuchess

Trigger words can be "jinmao" and/or "Jinshi and Maomao" (they seem to be making difference mostly just with photorealistic checkpoints at ClipSkip 1 though), but you can also use just "1girl, 1boy" and for more consistent hair colors "1girl with green hair, 1boy with purple hair" seem to be doing fine at ClipSkip 2 (of course color bleeding can't be completely avoided). Sample images made with CardosAnime, ArthemyComics, AbsoluteReality and ICBINP models, all at full LoRA weight.
