For someone to develop to what we call addult mind, that person needs experience, human interaction, emotional development, study, world experience.
A kid that stays in prison for the rest of her life only suffering abuse, Will remain with a kid mentality.
@Lilsoybean she's confined and abuses, so I think it stunt her development (especially the confinement).
We even have real case where a child go feral because of neglecting.
@lilsoybean I mean this is probably the one exception for childlike mc despite reincarnation considering she was basically shut in the hut her entire life with no social contact and abused, thus I doubt she has had the proper mental and emotional development to be mature
@Lilsoybean she's acting childish because she is mentally/emotionally a child. She was abused in her previous life and was not allowed to have human contact except for outside of her abusers, so she doesn't know a life outside of that yet. She's dealing with psychological wounds, too--she's eager to please those around her because she doesn't want them to hate her. It's not like those other stories where a 30 year old went back to when they were a kid. She never got to mature past the 7 year old/8 year old body because the abuse started then, so she's literally just went back to the start line.
The similarities of this and WMMAP is uncanny. I noticed a lot of korean webcomics do this... they copy each other, alter a few details and slap a different title on it. Solo leveling is a great example. There's so many variations of that story. This is not a bad read it's just predictable because it's been done before.
This is so cute omg!! The FL is really cute too. I have a feeling the FL’s mother forced a spell or something that made him forget. Or who knows she’s stuck in the sword of his? Since his sword accompanied him wherever he goes.
