Yesssss, (≧▽≦) she mentioned in one of the early chapters that if someone has gotten degree or (a high level of education) they can cut the ties with their family, and she did it, she literally became the youngest (i don't remember the name of field) ,by that logic she could very well change her name and leave the family registry, I still don't get why she is acting as if she is still part of family.¯_ಠ_ಠ_/¯
And another thing why can't she just directly tell the ml that she doesn't what her engagement yet ? I mean she is a strong confident women who is very good at her job, and is now taking care of the world tree.୧( ˵ ° ~ ° ˵ )୨
Maybe the fact that misogony is still present in the novel, and that the reason why "it doesn't matter if you are stong women and have a great job but if u r not married or have a guy in ur life you won't be happy" king of thinking is present in this story.乁| ・ ・ |ㄏ
I am reading this story cause I wanna know about the world tree but if a point came where the ml and fl become insufferable i might drop this.¯(◉‿◉)/¯

This story would've been more entertaining if the ML was not in the picture:) he acts like the male leads that readers usually eat up but he is written so badly he's like all over the place.
