So, first impression:
Overenergetic girl trying her best for her "hero"
Playboy MC fed up with everyones bs wants a new start.
Thus far relatively promising. I can see where others might be annoyed with the gal, but she's imo still a decent character because MC actually has something to earn her respect.
90% of the fantasy-adventure manga have a completely useless MC with thousands of girls creaming themselves because of his mere existence. This one has a rookie adventurer meet a legendary adventurer and fangirl over him. As long as she doesn't go the route of becoming nothing more than boobs that are obsessed with getting impregnated by him she's already in what feels like the top 3% of female representation in this genre.
And the Male MC is not a whimpy nice guy either driven mad by revenge or just having the plot happen to him. Top 5% for sure alone for that.
For real though, he seems interesting and actually deserving of the respect he gets.
So thus far, it looks promising.
