The female lead has been reborn a lot, as well as seeing her dead mom alive and then dying. The father is a man with black hair and she has 2 siblings; a girl and a boy with black hair and yellow eyes. The girl can summon the spirt of the moon as a butterfly and the sun as a snake. Her family has black hair with yellow eyes like a tiger.
The father meets the daughter after the child was brought by family friends, I think. The siblings meet her later.
She is scared of the stuff in her room and of the people. Such as the bathtub scene and where she eats, which is on the ground.
Later the fathers brother her uncle and her moms friend the king was someone she met multiples time. So when he sent a letter with gift she called the king by his name which only a few knew/spoke of. The family was confused as they didn't know how she knew.
Also the doctor she had was a lady who grew close to her as they aged and in the ending the doctor left to start her own clinic.
Also the moon healed her injuries where she had many broken bones all over her body in a instant.
The manhwa was updated recently showing her all group to few years older child/teen and her siblings were either teens/adults.
