I have a feeling that she (the mom) might be related to the emperor, so that's y this little girl got that special ability. So once the emperor gets screen time probably the mom will also be mentioned..... This is just a guess on my part so not a spoiler unless it becomes true hahaha
But then, she said that the primera was born outside of the imperial family yk
They probably aren't mentioning her in front of mc since they won't be able to meet (her mom is on the battlefield). Telling a child and arousing their curiosity when they can't meet is cruel
She might be a distant sister who was we'd to the Duke so now she is not a part of imperial family ....I'm not so sure either let's see
I get why they dont mention her bht what i’m saying is that it’s weird that even MC isnt thinking or talking about her, she might be in a child’s body but she’s grown. How does one go back home and not wonder who/where her mom is
I get that her mom probably isnt being mentioned as a mystery towards us readers but it’s still illogical for no one to talk about her, at least the princess should ask what happened to her. We dont have to get an answer, it can still stay anonymous but at least her existence should be mentioned
