Part 2 is a direct continuation of part 1, so there are minor spoilers.
Myne got successful and she got where she needed to be, but it wasn't enough for her. She decides it's in her best option to become a noble, where she can read books, develop her magic, and adjust to the social systems. This story arc felt more for her character development, pushing the narrative of her becoming basically overpowered, in a sense. Not only is she selfless, but she is also 1 step ahead of everyone-
I feel as though she is making the wrong decision, and in the next part
-SPOILERS-,
she will be leaving her family behind (for good this time) who supported her SO much in her journey and becoming adopted by a noble, forgetting where she started at (poor and ill, with a huge support system). Her goal remains the same, but the story has taken a detour. This is why I felt this enjoyment was a lot less than part 1
