It's been years so I only remember some details about this webtoon. It's about a girl who was killed by her father because of her half-sister, then she regressed. She now doesn't want to have anything to do with him, so she started to avoid her father. The fl has a younger brother who also died in her past life, and she's now protecting him.
It's about a girl who went back in time, she has 2 or 3 older sisters who all love and adore her. The eldest sister's ML is the emperor and the other sister's partner is the emperor's knight. The little girl is sickly so her 3rd sister asked a guy to cure her illness but the MC is scared of that guy. Sorry, I suck at explaining thanks in advance
I wouldn't mind if this manhwa has a thousand chapters.
