It’s My First Time Being Loved
Reincarnation. She has lived 99 lives where she dies before her 20th birthday. Only in the first life did she sacrifice herself willingly to save her friends. But in the others she was always destined to die even if she didn't want to. She kept getting abused and taken advantage off so she didn't hold many expectations in life. That's why she was surprised when she came into her 100th life and she was suddenly blessed with a loving family. She was reluctant at first but quickly opened up to them. She also befriended her brother's best friend the other little Duke. She has a familiar flying dog called choco who she is able to summon through all her reincarnations. She gets pulled into a mysterious being's landscape during her dreams and always wakes up with a fever, but I don't know if he's an enemy or a friend because he kind-of attacked her family. The little Dukegrandfather came to visit them and told them of the news of the Queen being pregnant even tho I don't know why they're such bad news that make them wary. It must have to do with a succession fight since the MC's mother apparently gave up the throne to the current king.
