I really like Lart honestly. Of course he's a young ass but the imperial bullshit like manipulation and putting on fronts are not there. It would be nice to see a redemption arc with him or something. Of course the younger sis is the mastermind or whatever so she can go rot a little. I'd also like dad to step up and change as well.
Nothing to say about the second romantic interest popping up since it'll only be there to make the plot come about prolly.
Also, WOW! A main character who is smart averagely, knows how to have a brain and still has bits of interesting trauma supporting her character. 90% of other webcomics with the same from nothing to someone/i returned time/reincarnation are dumber than her. So far the main character and her interactions with panther boy are really carrying the start of this.
