Cute, fluffy, main character that doesn't want to be abandoned and works to be accepted and it's not an isekai nor reincarnation stuff, main character is pure and innocent child.
After 5 chapters flag of danger is raised somewhere ahead but not anything dramatic and also who would pick a fight with a pack of gryphons.
I saw a comment that main character wants to garner pity but.. isn't it normal for a child that was just abandoned in the forest alone, friendly reminder: it's a child here, it's good she didn't burst out in tears and wail all day until got tired and fell asleep. (Also it's good she doesn't have any trauma or didn't close herself up from the outside world in fear of being hurt and abandoned again)
Why they hate one of their daughters. One is cute, smart and talented, while another is only cute.
I have not met any twins in my life and the concept of comparing one to another, saying one is more talented and/more gifted is probably only in medias like manga/anime or in enviroment that puts heavy expectations on the children like strict parents or just sick view of people living in the village which is unthinkable for those that can't understand this.
Personally I've heard of a mother that didn't feel any love or care for her child and just left it. It happened and even if it seems like a bad storyline, it is one that is very realistic and deprived of all logic.
Also I definitely am not a keyboard warrior. I read and type on a smartphone!
