This is my experemental concept. I couldn't generate a similar pose and couldn't find a lore for similar images.

The concept is fully experimental and some bugs are possible, I haven't tested it fully yet. I apologize in advance for any problems caused.

Test positive prompt:

POVKissH, 1boy, couple, kissing_her_fingers, hold_her_hand, masterpiece, best quality, amazing quality, very aesthetic, absundres

Test negative prompt:

worst quality, bad quality, very displeasing, displeasing, bad anatomy, artistic error, lowres, bad hands, signature, artist name, multiple views, variations, old, oldest, missing fingers, excess fingers, extra hands, excess hands

ANOTHER TEST

Running lora tests on my standard style, I found that in my case the best generation occurs with about this structure:

POVKissH, 1boy, couple, kissing_her_fingers, hold_her_hand, (these are the triggers for the pose)

grabb hands, girl out frame (these tags help generate a better hand, but depends on your prompt),
best quality, newest, highres, absurdres, masterpiece, cinematic lighting, - quality tags
upper body, - specify which frame we want.

Next comes the appearance of your character. Describe the character only from the waist up. Enhancing appearance tags like detailed eyes, detailed face in my case broke the pose

BREAK background, detailed background, 2.5d, oth3rc1de, v0x - and here I'm writing style tags and detailing the background.

And that clue looks like this:

POVKissH, 1boy, couple, kissing_her_fingers, hold_her_hand, grabb hands, girl out frame, best quality, newest, highres, absurdres, masterpiece, cinematic lighting, upper body, __YOU CHAR PROMT__

BREAK
background, detailed background, __STYLE TRIGGERS__

Frequent Problems:

Hand 2 characters, if you need someone specific, it's better to fix inpaint.

Some LORA and Negative embending may not work correctly and pic will need to be corrected with inpaint
