One of my favorite manhwa! It is very interesting and the storyline draws you in more, however it does get frustrating at some chapters. Basically, she gets reincarnated as a baby in a fantasy “book” and her father had never loved her in her previous life and even killed her so she set out to make sure that she would be able to survive but instead gets sucked into a different route then she wanted. ch 89
