The "villain" side seems to have a lot of likeable characters while the "hero" side is a bit mixed. The saintess seems sketchy, the fiance is a mess, the King's a pretty reasonable lad, the prince is an absolute (ey) prick, and the hero is the shining example of a nob head.
How's the web novel, for the people who already read it? Do these characters have developments, growths, and changes as it goes on or is this gonna be the typical villain isekai but the roles are reversed story? Just setting expectations.
