This LoRA was trained on Lee Ru-ha, one of the lead actresses in “Today's Han Yo-il is a Woman (Who's that girl?)”.
I recommend setting the strength to 1, but if there are any issues, lowering it to 0.8–0.9 will still produce a good Character.
Since the character’s outfit changes so frequently in the original comic, there is no standard costume.
However, if you describe the character's costume from the manhwa well in the prompt, it should be possible to achieve a reasonably similar result.
Lee Ru-ha has hairstyles where both ears are visible and others where only one ear is visible. (They're subtly different 🤣)
When you want both ears to be visible, use only 'ru-ha, red eyes, long hair, grey hair, pink hair, gradient hair, parted bangs, curtained hair, straight hair' in the prompt.
To conceal one ear, use “ru-ha, red eyes, long hair, grey hair, pink hair, gradient hair, parted bangs, curtained hair, straight hair, asymmetrical bangs, one ear visible” in the prompt.
