I've only read up to chapter 38, but let me tell you this story is way better then the syponis explains it.
Estelle goes through child abuse as a child by her mother, and she seems to think thats normal. She gets sold to the Duke Ein, her father, for 20,000 gold. She finally gets a family, with her brother Karl being kind as well as her father and the knights that protect her. Theres much more to it but you should read it first seeing as how my heart almost audibly went 'KYAAAA' when reading this lmao. But I really do recomend!
