I recommend you go with lora strength 1. this lora is specifically made for making images where 2girls kissing a boy. I have tried to make this type of lora before, but it is is hard ( the lora: https://civitai.com/models/610095/kissing-cheeks). I recommend you copying my prompt because this lora need specific keywords to trigger the concept.
