This LoRA puts the heart-eyes emoji on top of faces. It's a bit experimental and not perfect. No trigger words.

Use weight around 0.8 -1.2 range. When weight is too low, you will see horrors. When weight is too high the emoji gets messed up (extra eyes and other distortions).

For small/distant faces you will need to use hi.res fix or another SD upscaler, because without upscaling the hearts will look like circles or the entire emoji will just be distorted.

Probably doesn't work for anime models but you can try with higher weight. I tried and couldn't get very good results.
